that should be one sick build. im just leary on the stock heads being milled with lifting since they deck is much smaller now.. however i dont see 1 reason why this wont be a successful outcome

as was i but by running the LS9 head gasket i hopefully took care of that issue... .070 vs .051 and that sticks me at a 9.6:1 CR

.7 is pretty damm thick for a gasket. you have any idea on what your quench is now?

lol that is .070 quenched...they are a 9 layer MLS gasket...badass gasket and come on the ZR-1 so you know they are designed for a lot of boost

no no not the gasket compressed. im saying the CC quench. i know when you run a thinner then stock gasket the quench goes up and less chance of detonation. Just curious cause ive read where ppl double stack gaskets to say .8 and run into detonation issues.. thats my concern

Good stuff man. That motor looks awesome. Can't wait to see how the old dog likes it.

[mean05]

Ah yeah i have no idea on that...just talked with a few diff builders and they all said i should be okay...i only plan on 18psi ish
