Everyone on turbomustangs(theturboforums) recommends the 9333s.

I am running the Felpro 1011-2's with ARP bolts on 302 w/GT40P's for 2 years now, with 15-17 lbs boost and no problems. I do not race it, but it gets the #### stomped out of it almost everytime I get in it.

Made 486 rwhp on the dyno last August in 96.57 deg heat!

Orginal stock shortblock.

all my car was just pressurizing the cooling system,i see some people say no more than 10psi with iron heads, but you say you are running 15-17psi and she is living...maby i can give it anther shot with thses and a 1011-2 gaskets...

i could drive it all day long and it was fine until i made some boost,then it would fill up the overflow...

Been beating mine up for over a year now with Fel 9333's. I also wonder how much boost mine will take before she spits out parts. Combo in sig.

Stock block, GT40 heads, Explorer intake, 67mm, 10lbs, 431HP 497TQ on 110 octane. 12.01 @ 123

I run 11-12psi through dooe heads (same as gt40s...kinda). No coolant problems. I run felpro stock replacements and e85/F-cam. In the process of switching out for the eddy heads and felpro 9333s right now.

How did you tune it? Sure it didn't detonate and you just found it?

well it may have detonated before i got it tuned, because i took it out to see where the wastegate was but it had the spout out and was on 10 degrees...i know pumpgas will very from place to place, so it will just get race gas until i can get some good heads...I also took out 1psi of boost..

Iron heads and amount of boost is not really related or not near as much as deck thickness. I ran 18lbs with iron Dart Sr heads and never one single issue. I ran 12lbs with old school gt40 heads and had a lot of issues. My issues though were from the heads being milled down and causing me to have an even thinner deck. In both cases I ran the old felpro 1006 gaskets.

Yo Aaron! You got any idea how thick the decks are on say AFR 165's or TW's? I ran TW's w/o problems before, but I thought about maybe trying AFR's this time.

Bobo, I do not know anything about the AFRs. I have seen a number of people run various AFR selections but just never bothered to learn anything about them. Matter of fact I think perhaps Trent first ran them with his old turbo GT but I could be wrong on that. I'd hope the deck is just fine on them and the bigger worry I'd have is what would the compression ration be with them.

I thought Trent had some head problems back in the day, maybe it was with iron heads? I forget now

I think the TW's are 61 cc and the 165's 60 cc. I actually bought a set of 205's years ago....I think I was going to build a 408...I think lol. Damn memory. OCD + ADHD and I can't keep up with myself. But I haven't looked much at the smaller heads.

For some reason I've decided to almost redo a combo I did 10+ years ago, but maybe with some better parts and newer technology.

He always had Al heads, but I think he started with AFRs but I might be wrong. I'd go with opened up TWs.

Oh sorry to hijack the thread Conbread I know my buddy kept blowing gaskets with his GT40 irons and a Vortech. So that's not much info for your questions, but maybe you can save up for some aluminums that'll make more hp and hopefully keep you from opening up the motor again. More powah!

Aaron, I loved my old TW's, but I'll study up a bit on the 165's as I kind want to give them a chance. I thought the 185's were more along the lines of the TW's, but require fly cutting (not sure if I'd want to try my hand at that).
