ARP 625's AGAIN............

Great way to waste $800 in an application that does not warrant them.

I must have missed all the lifted head threads where people were using ARP 2000's?
I only know of 1 motor that actually lifted it's heads - and that was Tino's monster!

Head studs won't fix bore resonance - I'd be pinning the top of the 2.5's bores before throwing Primo Guucci head studs at it.

BTW I do rate the 625's - I just fitted a set to an RB26 that makes 950hp, they are just complete wank on mild builds.
