Re-torquing ARP headstuds

Heres how you do it... Buy some L19s from me, remove the head, put in a new HG without copper spray, and torque to spec.

ok, did we discuss copper/no copper last time I did this? What's the advantage of going no copper? And can you remind me what we discussed for torque? This is a 7-bolt, I think I did 87 or 88 lb-ft last time.

Shane, I think you hit the nail on the head, but I'd like to take 30 mins and try this re-torquing first, just for giggles.

I second that!

Also, how old is your coolant cap? I had a friend with a 2g that would push the coolant into the over flow at 24psi with an fp green. We swapped to L19's and fel pro head gasket and still, it would push coolant.

Installed a coolant cap from Nissan 300zx, problem solved. I think the coolant was being heated and expanded so quickly that it was making pressure and pushing the old, worn-out cap open.

Just a thought . . .
