How many of you guys run the 625 ARP's? How many are having problems with the regular ARP's clamping the heads down enough? How are the A-1 head studs? I need something better than the regular ARP studs that I now run. Please give me some feedback.
I was wondering the same thing , motor is apart and was wondering should I upgrade .

What cam do you have now.
With triples we had to upgrade to the 625 arp.
I just put the 625's in from the get go, seemed like cheap insurance to me.
Regular arp studs here with 90+ of boost so far so good
What are you lb7 guys doing for injector cups? I have a feeling i have one pressurizing the cooling system.
