Power with stock TTY headbolts?
Power with stock TTY headbolts? im not really looking for XX psi is all they take but more power level they have survived at. hitting the dyno in the morning and wondering were i should stop. stock truck cam/92 octane numbers in sig. i have put a mild custom cam in it and have 15 gallons of e85 going in the car. will most likely stay at current boost level but MIGHT go up depending on how things are going. i do plan on studs but probably wont happen till the winter
I've reread those first two sentences over and over and I'm still not quite sure what you're asking. lol If you're at 15 psi on the stock head bolts, I certainly wouldn't go any higher. Bob

No one can tell you how long it will survive at 15 or more boost. The simple fact is you are asking every moving part to perform way out of their safe design limits. You are living on the edge.

ive had great luck with all 4.8 5.3 and 6.0 motors right up to and a little over 20psi on stock gaskets, bolts etc.
they are beasts
i am always conservative on timing and pumpgas+meth for safety
when it quits making good power with timing i quit.
sometimes... lol

It's power/cyl psi not just boost psi that does it. For me mid 10's/high 12xmph will lift them after awhile in my 4850LB truck. That's around 16psi. In a lighter chassis you might get away with a bit more.
