dropping compression??

Hey guys I am putting soon a turbo setup on a stock short block and was wondering what is the lowest C/R I can go with by using a 6.0 truck heads? what head gasket?

i am hoping for somewhere between 9:1 to 9:5.

Thanks!

0.067 cometic gasket is the thickest thing u can go with not having quench problems. If my calculations are right u will be at 9:2 CR.

stock MLS 6.0L gaskets will drop compression to about 9.4/1..
