its a water jacket,looks like it was going right into lifter valley?,and thats the only cylinder that has some white on it?.....i really hope that didnt happen when i took it off!....i only did one head gasket before on a 4 banger and it was blown out the middle,so that was 100% definitive.

Im no expert reading head gaskets, but those look like felpro 1011s, which tend to not like boost. If the experts here can tell if that is your problem, change to 9333s, they take a bunch more abuse and are slightly thicker.

9333 pt1 are a good stock replacement gasket that can take abuse with some boost . That gasket doesn't look healthy and white on the.cyl says that's prob your issue . I'd stay away from MLs gaskets on your car cuz as you see the gasket was the fusible link in the situation .

a touch, the 9333 is .008" thicker than a 1011. i dont know the full specs on your motor, but running the calcs on mine the 1011 is 9.65:1 and the 9333 is 9.44:1

Yes. Not sure on that particular gasket you were running(thickness wise) but get the thickest one you can get and it will lower your compression. That gasket/head looks like it was bad. So hopefully you found your problem. And I also recommend the 9333's. Good luck!

If he sprang for a MLs deal he could take some more squeeze out of the motor too. Just with a stock block I don't know if a MLs gasket is ideal

I only read to certain point and skimmed the rest. This response may no longer be relevant (I'm on page 16 moving forward).

Have you removed and looked at the timing cover for cracks etc?

--also--

Aftermarket heads leave a gap between it and the block right at the corners of where the cork gasket should be sitting if you used one. That gap has to be filled from behind/underneath the lip of the deck and bottom of the head.

Mls gaskets tend to need a very particular and very flat surface finish, a lot easier to do with a fresh build. A traditional style gasket (1011, 9333, etc ) is a bit more "forgiving."

At this point, since you have it halfway apart anyway, I'd pull the cover and just double check everything is in one piece. Make sure the front bulhead isn't cracked, or you don't have a leaky gasket.

Ok.....well i talked to the other tuner,he also recomended the mls,and he said if i was runing 9 psi i should get a meth kit,but if im running 6psi ill be fine with out one,my funds are depleating,so for now im going with a mild tune!

Unless you get the block and head PERFECTLY straight and they are prepped for them., don't get MLS gaskets. I've run 9333pt1's on every mustang I;ve owned for 25 years and they are fine.. They have a better fire ring than the 1011's and IMO you want the head gasket to be the fuse in the system.

Check the block and heads for straightness while eveything apart and get the surfaces squeaky clean using razor blades, green scotchbrites. I don;t like whiz wheels on aluminum. Make sure you put the HG on so both front go to the front and look up- one will look wierd but it does go that way.

Yes these guys are right with the surface needing to be prepped right to seal
