Putting an end to the the Pro Comp head mystery-*many pics in here*

[nidyanazo]

These are the 190cc versions, sent to me by Jim at tri state. I spoke to him for a while, and he had lots of good things to say. He does the machine work and assembles them. I think one of the reasons many people complain of thier lack of quality is because they buy them bare, (THEN YOU HAVE TO DO THE MACHINE WORK ON THEM). The fit and finish is excellent. I'm using crane 1.6 rockers, and the geometry is on. Checked piston to valve clearance for the custom lunati cam I just got, and it checks out fine. I tried to get some up close detail of the ports and chambers, but my camera wont foucs very well.
All in all I am very pleased with them, and hope people will stop bashing them as "junk". (I tossed in a pic of my intake with new 30lb.hr venom injectors)
Any questions?

They look pretty nice to me...

[Dennis111]

Did you use the Chevy or the Ford 1.6 rockers?

How was your valve cover fit on your 190's?

I've ran the Pro Comp 210's all summer on my and have been pleased with them. They also came from Tri-State. I got them with PEP severe duty Chevy valves and added my own springs, retainers, locks, and rocker arm studs. I also had them thoroughly double checked by my local performance machine shop to ensure that they were indeed useable.

I found that the area under the valve seat was not not pocket ported and cleaned them up with my dremel.

Let us know how it runs at the track, congrats. How much was an assembled set from tri-state? I think the arguement may be the cost involved once they are assembled compared to a proven head like the Victor Jr. I believe someone posted the difference in price once you do all the assembly, with quality parts, etc..... Not a huge savings. Hopefully they work out for you. I was going to purchase some to try them out but I read so much negative stuff that I decided to wait and buy my third set of Vic Jrs. I found a set a few weeks ago for 800.00 with less than 300 miles on them. Let us know.

I used Crane CRN-11746-16 rockers, says they fit AMC/CHEVY/FORD...

I will post how well they do for sure...
Might be some time though till the car is ready though.
Now I need some 6.750" pushrods and lifters.
I got them Shipped for $874...

[wldtang]

Tri State is like 5 min. from my house. I have went over there to speak with Jim. Very nice guy.

[nidyanazo]

Here is a closeup of the port allignment....Some people have seemed to have problems in this area, iverything is fine using a trickflow piece..


And how they look on the motor..

[racerxmd]

O.K. about 900.00 for the set shipped? How much for Tri-State to set them up and any machine work?

I see your point but the Vic Jrs. do not come with the best parts from Edelbrock either. You get a couple of spring choices that may or may not work for your cam. The pressures may be wrong or the installed height may be off. If you are going to purchase the recommended springs for a specific cam, you will have even more invested in the Vics.

I have barely $900 in my Pro Comps (which were purchased bare) using PEP Severe Duty Valves (which are "supposed" to better than what Edelbrock supplys on the standard Vic Jrs.), the premium upgrade Comp Cams springs that match my cam, Comp retainers and locks, ARP rocker studs, and the Isky adjustable guide plates. Also included in the price was a 5 angle valve job and head check out at the local high performance engine builder.

The pocket porting I did was basically free since I owned the flex drive dremel and had a couple of hours of time to kill.

You don't necessarily get more value using the Vics, but I still think the Vic Jrs are a heck of a bargain at around $1000 because you get a factory warantee which you will not get with the Pro Comps. The Pro Comps are buyer beware so if you consider them, be sure to get them from a reputable dealer.

Yes, I can straddle both sides of the fence.

I got mine for $874, shipped, with the machine work, just as they are in the pictures.

[Ltngdrvr]

There's a store on ebay selling complete sets for $699, they don't call them pro-comps but that's what they are.

They look okay to me and most as cast ports in aluminum heads could use some clean up, that's nothing new or worrysome.

[351Freak]

welcome to the club...

I should have mine running speed density with the AEM in the next week or so...had it running mass air/PMS but the intake gasket sprung a leak and the head gaskets never sealed...

it's back together now and in the car...maybe it'll fire next weekend...

should be a mean mofo if all goes well...

good luck on yours...post results when you can...

[damage]

People are actually complaining about a $500/pair bare aluminum cylinder head?

[MACDRIVE]

Nice sideburns.

[Danglerb]

Some people would complain if you hang them with a new rope.

Honestly

[Linc's 93 Splash]

It's nice to see a success story. I have still yet to use mine

[5.0mustang5speed]

pro comp...protop line..rhc...all the same head..from new zeland..i have the name pro top line heads on mine..the 200cc version..i had mine fully worked and i would put them up against a head that cost 2 times as much

[nidyanazo]

And an update:
They make awesome power in the upper rpm range, lower torque is down (but I swapped in a 228/232* @0.50" cam at the same time...I really like these heads, and think they were an excellent deal. Only complaint is the guideplates didnt allign exactly right, so I clearanced them, which ended up making them too big, so the fix was isky adj. guideplates. ($51)
Look great also!

I'm right there with ya bro!

These do seem to be a great deal for the price, I am all about bang for the buck. Is this the same heads that Livernois sells? A buddy of minre just got a pair from them.

BTW cant remember the last time I saw cast iron water pump! Beechin!

Pro Topline did go out of business last year, but have since been bought out Comp Cams. They are now in the process of retooling the Pro Topline head and will be selling them under the RHS brand, which stands for Racing Head Service. You can read all about the new Pro Topline heads here:

[89white50]

pro-topline was bought out by comp cams and is now RHS, and is not the same as the ProComps.

[JBeezy53]

So what heads are these 190cc heads modeled after?

I have the same heads and although my project is on hold for quite a while ($ has kept me from working on it in months), I'm wondering how these didn't give you valve cover problems. I tried using cork gaskets as the blue rubber felpro's don't even come close to lining up. I also tried using the stock valve covers from my 95 as well as some fox body valve covers with no luck. What valve covers and gaskets are using so that this all works out? If you wanna see what I'm talking about, check out my posts in the pro-comp thread for pics so you can see how bad it is on mine. Hopefully you have the answer to the question thats been keeping me up a night!

I used 2 cork gaskets. Some gasket sealer, and ground down the inside of the stock (1986 aluminum) valvecovers. That gets me enough clearance, and no oil leaks.

Also- as an update the car has been running great ever since I built another motor (I did a thread on it called "How to build an engine") and I have got to say: I love the heads. I think my intake is holding me back, because it makes peak power around 5700rpm, but wants to rev to 6K.

[Trey LePark]

So given your experience with these heads do you think these :http://www.tristatecylinderhead.com/...roducts_id=106 would be good for a simple HCI combo on a stock block? I also have a Explorer intake and TB, Flowtech headers etc.. with no EGR. The cam will be a custom to match the combo. I thought about getting their GT-40 heads but when you add in the price of GT-40 specific headers it's the same price or cheaper for the Tri-Pros.

[nidyanazo]

Those are the ones I have.
They are great. Trust me.
I would make sure you have a cam with a good amount of duration.
And a bigger intake.
If you are going to use that intake, get a cam with power peak around 5500rpm.

These ebay stores are selling the heads assembled with the cheapest valves/springs/seals money can buy. If i was buying them i would get them from a reputable seller like tri state.

Thanks, that's good news. This is a major budget build so I'm going to stick with the Explorer intake I have. The power band I'm looking for is under 6k RPM so it'll be whatever EC/JA/BR calls for. The hardest part will be picking out one of those 3 to grind the cam.

That is why I bought mine bare.
