Should it even be a concern with 650 rwhp and a great safe street tune? I have ARP head studs not the oversize ones. Not exactly sure what head gasket just know it is slightly thicker than stock. Thanks!

I made 590RWHP at 10psi, stupid rich, and run 15-16psi on pump and meth on the street at about 18deg peak timing and like the 'spirited' driving I have ARP studs, MLS gaskets, TEA stage 2 heads, comp 228/228 116, but I'm at 8.5:1 static CR... I have had it up to 18 psi through 2-3 gears 8-9 times with good (leaded) fuel. I haven't pushed any water and it feels GOOD.

I have a little over 60,000 miles on my truck with 600 at the tires(4/AWD). I have had the heads off once about 20,000 ago and everything looked good. I use a factory MLS and stock bolts.
