Felpro Intake gaskets stock MS93334 vs GT40 MS95952 comparison. (Lots of pics!!!)

I searched for this information for quite some time and was unable to find it anywhere. I now have both sets and decided to post the info about both.

This is a comparison between Felpro Part # MS93334 for stock heads and intake and Felpro Part # MS95952 for GT40 heads and intake.

The MS 93334 came from Summit and the MS 95952 came from Rock Auto. Both sets were purchased in 2009. They both include the distributor O-ring. I had already used one of the O-rings by the time the pics had been taken.

Now for the specific information I wasn't able to find that I want to provide here.

MS93334
Intake port size Width 1.15" x Height 1.96"
Has later water passages.
Very high quality

Includes gaskets#
5511 Distributor O-ring
90361 intake gaskets
93334 Upper to lower
94059 IAC gasket
95504 Intake manifold to block front
95505 Intake manifold to block rear


MS95952
Intake port size Width 1.28" x Height 1.98"
Has later water passages.
Not real impressed with the Intake gaskets. Not as high quality as the other set. Different material used in intake gaskets.

Includes gaskets#
5511 Distributor O-ring
94059 IAC gasket
95504 Intake manifold to block front
95505 Intake manifold to block rear
95952 intake gaskets
95953 Upper to lower


MS95952 on the left. MS93334 on the right.

I run the MS93334. I have Ported E7's and Cobra Intake. The gaskets are just the right size for the port, perhaps a tad too small, but like you noted the quality is very good. I had a bad leak running the 1250 since those have zero metal in them, its hard to keep them in place when putting it together.

I would give the other a try though. I also use the rubber end seals, I think they work great.

Are the intake-to-head gaskets specific to the intake, or specific to the heads? As in, would the intake-to-head gaskets from the either kit work with a GT40 intake and E7 heads?

Without making a blanket statement, the answer is yes, either of these will work. What most guys like to do is get gaskets that are the same port size as the heads so that flow is not hurt by the smaller gaskets.

In best case senario, heads are ported to gasket, and the lower intake is ported to the same gasket.

I've been saying this for years. The 93334 kit has steel core gaskets and the 95952 does not. I've been using the 93334 kits for years and just buying the upper-lower gakset seperate if I need it. The 93334 kit is cheaper too. If your head has a port larger than the 1.15"x1.96" then try the 95952 kit - it's not a "bad" kit, I just like the other better.

Well I wish you had posted that earlier. The 95952 is now on the car and no longer available for testing. Are you sure about them not being steel cored? I just assumed they were.

Anyway after I got the ported lower back from you I switched to Iron GT40 heads instead of the AFR's. The GT40 heads I used were half assed ported by someone who apparently used the 95952 as a guide as it matched perfectly. I would have preferred to use the 93334 but I wasn't sure if cutting into the raised portion of the gasket outlining the gasket was a good idea from a sealing standpoint. I also have no desire to try to trim a steel core gasket.

I think you did the right thing. Opening the port at the flange face did about zero for head port flow - the limitations are in the pushrod pinch and valve bowl/throat areas.

This is a really good post with some good pics so I figured I would add some info to it. In another post someone said that the Edelbrock intake gaskets are steel core because the Summit page said they were. I was ordering some stuff so I figured I would a set just to see. They are junk, no steel core.





Compared to the 90361 gasket:

Just double checking, the 95952 does not have a steel core?

Also, I've capped my thermactor holes on the back of my heads (gt40 y's). Do I need to use a gasket that provides the pieces to cover the egr holes on the heads? If it matters, the car stills has the EGR valve but no other smog equipment.

Thanks,

95952 aren't steel core, are you sure??? I just bought some and they seem to have a steel layer to them....

RockAuto tends to agree...

What's the big deal on the steel core? Never saw the need for that unless there's no material at the lower section of the runner after porting but these are tiny entrances so how bad can it be to use a normal gasket material?

the 1250 is a impregnated paper gasket and I've seen personally and pictures online of how they absorb water/oil and get soft, then get deformed and sucked into the runner from vacuum exposure. Pics have been on this forum before. This may beg the question for re-torquing after heat cycles like I do 2-3 times but not many guys do that. If you don't have a gasket from the stock replacement 93334 Fel Pro kit, Ed, get one and I bet you'll see quite a difference in rigidity and quality. That's my experience, anyway.

An old thread, but worth a reminder. This is why non-steel cores suck:



This was the "good" one - the other side had completely disintegrated. That's a Fel-pro "performance" gasket, btw. Might be ok if you're pulling your intake every few months, but I try not to do that.

I've always like the stock gaskets the best (by far), but you need to "port" them with any reasonable head - and that can be a PITA. I'll be giving the explorer ones a shot this time, since they're in my garage now...

I have a set on the shelf, they are not. Maybe they changed them since I bought this set. Sure you don't have the 1250S3 gasket set?

I just had this happen to me, was kinda shocked when I saw it and was wondering about the clamping force having anything to do with it. You ought to send FelPro the pic and see what they say about it.

The 1250 ans 1262 have been falling apart like that for years and years. I think Fel Pro probably knows about it by now.

https://www.google.com/search?q=felp...oe=utf-8&aq=t&

Besides, I don't think it's a design flaw. IMO, they were probably marketed as a low-cost gasket for racers that replace them frequently and after far less usage than any typical street car sees.

So the big question is, which gaskets are the ones to use?

And the answer has always been:

For a street engine, steel core.

For a race engine, whatever you want.

Great post and yes another old bump to the thread. I'm about to have to pull my intake off for what I'm pretty sure is a shot end gasket. I don't have enough confidence to do rtv only so I was going to go the rubber route.

Mods are in my sig, so this 95952 should do the trick right?

Use the "Right stuff" instead of the end gaskets. It is made by Permatex and it works fantastic in this application.

Yep, This stuff works incredible. Thicker and stickier than RTV. A little $$$, but worth it!!

Okay I'm gonna listen to the folks that know much more than me. I'm pretty mechanically challenged but ready to slowly learn. I just can't get over the paranoia of having a nice car and attempting something on my own and seriously screwing something up. I did get my quad shocks removed today so that was a little victory for me ha.

I am going to probably be doing this intake removal solo. I have a Haynes manual, should that be enough to get me through this? I've tried looking online but surprisingly haven't come across a post or site with detailed instructions with pictures for the full retards like myself.

I've used the MS95952 gasket several time with great success. The ports are pretty much the same size as the 1250 gasket (which match the size of the ports on Edelbrock heads). I always use the rubber end seals. I've yet to have a leak.

You got the manual and what sounds like common sense, take your time and you will be fine. Snap a few detailed pics of all the electrical and vacuum connections before you start removing anything so you can look at them for reference later and also use some tape and number the injector wires so there is no second guessing during the re-install. Good luck!

Its easier than using gaskets, in my opinion. Here's a pic of my TW170's with 1260S3 gaskets and The Right Stuff on the front of the intake before I layed it down.

Not the best pic, but you get the idea. I would never try using the end gaskets.




ETA: I also did a thin smear of black RTV around the coolant passages.
