ZC tech
 

A buddy of mine told me i could use two standard 89 teg gaskets on my ZC to withstand boost, and it would lower my compression a little. Is this true, is this safe.

This is true, but not safe. It raises the chances of blowing a head gasket while lowering your compression. I say just boost it how it is. :-\

Agreed, Stacking Head gaskets is a Ghetto way to do it...Almost too ghetto for HMT...just do a better job tuning, or replace with a thicker metal HG

Thanks for the info, thought it might not be the best, but wanted some other opinions.
