Go metal gasket Either OEM gen3, Cometic, Toda, SCE (copper), ACL (race), HKS spring to mind ARP studs will also help - they are stronger and distort the bores less, but the price...... I'm also a firm believer in copper gasket spray, helps sealing and the gasket can be re-used over & over without a mess to clean up ie. the fibre gasket in my car has been used twice before - I practice what I preach! This stuff is awesome - just don't ask me why Weird thing is when you lift the head there's no sign of the copper but the gasket hasn't stuck
Ive got ARP studs for both the mains and the head. I was leaning towards cometic, because they are made only less than a hour away from me.(Been bugging them for a discount). Ive also found Apexi but they are almost triple what Cometic wants. I know the old saying goes, you get what you pay for and Im not about to scrimp when Im going have close to 5k USD in just the short block and head.
cometic. i use it, esraceing uses it, SRT use them, Paradise racing use them, every engine build i do i use them whether it's for a normal customer at work or performance work, i even believe screaming eagle use them.
Well, I went with cometic today. I ordered a complete engine gasket kit from them. Should be ready for me to pickup within a week since they are made to order. I pretty much drive by their HQ everyday for work, them and wiseco. Awhile back when I got my pistons, I got a cool tour of the wiseco facility.
