Why are you getting 625+'s?

Complete overkill for your application...... 625+'s are $700 worth of head studs......Great if you can run 35Psi of boost - a waste unless you are sleeving & close decking the cases.

The ARP 260-4701 head studs are what I have in mine ($280) - I run 1.7 bar daily & rev it to 8500 rpm - the heads have not lifted in 4 years......... On OEM head gaskets too.

I also have the ARP case bolts 260-5401 ($550) - Which add crank case rigidity - a far better investment imho.
