Does anybody remember part number for ARP head studs for 2.0 ?
I am rebuilding my motor for Martini . Installing Euro spec pistons and planning to deck the bloc 1MM. Want to make sure that I have good studs for it.

Yeah, I got them recently direct from JEGS... description was "ARP Head Studs w/12-Point Nuts (U/Cut Studs) 2.0L DOHC Cosworth Sierra/Escort M12" and they're currently listing for $135.99:

Edit, Summit has 'em a few bucks cheaper, $131:

...though I often find Summit's website more trouble than its worth...

That's a nice find, weren't these hard to come by?

No, it's the rod bolts that're hard to come by. Those were the Ideola-only kit.
