Stock head gasket and TTY bolt limit At what point do you throw gaskets and studs/bolts on these engines? How long did your stock head gaskets last and at what hp and/or boost?
ive built plenty of 10 second rides with regular gaskets and tty bolts
pumpgas also
hell my one build was a paper headgasketed 99 4.8 with stock tty bolts, pumpgas, 18psi went 10.72@136mph on a measly 1.75 60ft...

But why? For something so cheap - Its just a matter of time. Can it be done? Sure - but again, why?

If for any reason ur pulling the heads then go ahead and swap to head studs but if not I would just leave the motor alone and boost it denmah has pushed plenty of motors for us on stock stuff and has lifted a head that I'm aware of

Interesting results...
Only reason I ask is that you have to wonder if taking the heads off causing more problems than just leaving them on and keeping boost low and the tune-up where it needs to be. This LQ9 I'm starring at has the layered gaskets on it already from the factory.

Mine lifted at 630hp. Had 19* in it on E85 which isnt much for that fuel but they lifted. Its setup/tune dependent. I question whether or not the guy before had the heads off and reused the bolts though.
