ouch nothing. I thought a couple of guys in here were using those heads.....

They are good heads but you will have to get them port matched if you want to use them with a pi intake.

I doubt it was the tune , Justin knows his s**t . what exactly failed in the engine ? I would suspect your 11 yr old engine was weak & w/ cylinder pressure above 1000psi it just couldn't handle it . the hypereutectic pistons & powdered metal rods cant handle much more psi than that ,especially if you want it to last .

Yeah that's what I thought because Justin seems to know what he's doing and he looked really professional to me. It was actually the heads what broke, but my mechanic suggested to upgrade the internals of the engine to do it right once and for all.

Heads? ok maybe it wasnt the tune, but if it wasnt the heads it would have been the tune.

What broke on the heads?

I don't know exactly what broke on the heads but two spark plugs are fried, and the compression is also really bad on those two cilinders, and there's more water in the engine than the radiator. Hey thanks a lot OXFORDGT I really appreciate all your help, I check the websites you mentioned and I think I'll go with MMR they look professional and the prices are not that bad, you're pretty much the only one who answered this whole thread, that's to show you that one person could make a difference. Thanks for everything

Well you either have a blown head gasket of a hole in your block. Thats the only way to get water in the cylinder. I would do a tear down before you buy anything. Your heads are probably still good and if it was just a blown head gasket your shortblock is still good and only need to replace $100 gaskets.

Id check another Mechanic......See what they say, it might not be TOOOO bad. But if u have the cash to Throw in a Built motor Go for it

Is stage II heads and cams too much for a daily driven stang. I need a combo that supports the procharger but at the same time that would last a while since I still have a couple of years left in College.
