Thread: Who is running ARP head studs???

yes.

Friend is using ARP studs and Felpro head gaskets and DD's 20psi T-66 Turbo set up, along with a 23-25psi happy mode. Never hurt the head gaskets (yet). Broke a few 15/16" chains though .....

That is definately what I am looking for, thanks! I wasnt sure the limit that guys were pushing the stock/felpros and thought it was upper teens in boost but it makes me feel better seeing the 20 number as someone else is doing it.

That's on an L26 as well, so there's some serious pressure invovled.

High power applications need more clamping force, which is granted with arp studs. TTY bolts will just stretch and never really torque more then they are designed to. We dont want to be lifting heads now do we?

So just how hard is it to get these to seal? I hear about needing a lot of teflon tape. Just curious if it's something I may want to do.
