so i saw that cometic head gaskets are up for sale now. i read that the stock thickness is .060, which with my current setup with heads yields about a 9.1:1 cr. if i wanted to bump it up, what thickness would yield ~ 10:1 or 10.5:1? are the gaskets more prone to failing with them being that thin? also would head studs be recommended at this point? i have head bolts right now since cr is so low.

They are not more prone to failure at a thinner thickness. Head bolts should be fine but the ARP head studs will provide better clamping force. Really not necessary on NA at 10.5:1.
You cannot go thinner on the stock pistons or you will have piston to head contact issues at higher RPM. You need new pistons to hit that compression.Ben
