Again, i broke a ring land. this 12.8:1 business is a tough one; what is everyones experiences with stacking headgaskets? Equal amounts of people who are for it seem to be against it- i have been talking to a few people who ran it with no problems...if i stack 2 .037 y8 gaskets, i end up with 11.4:1 cr, a little easier to deal with. if i decinde to not do this, i will hve to make my tuning ultra clean to keep this from happening, but it would be so much easier for this daily driverr to have 11.4:1...

 

I'd buy an aftermarket thicker head gasket rather than using 2 gaskets stacked.

 

i have used extra black layers before..sealed fine. i was in the same boat as u. just make sure u take out the copper rings on the gaskets.
