Anyone out there running firerings with the regular 12mm studs? I have all the parts to do the firering just starting to wonder if the studs will be enough to crush the firering. Or should I send the A-1's back for some H-11's or 625's?
 
I have the Haisley head gasket set that has the firerings. I am using a set of standard ARP studs and it is holding fine.
 
ive got the standard 12mm's from arp and firerings. been drivin on it for a yr with ZERO problems!
 
Good to hear! Dropped the head off today.. What are you guys running for timing? Tow rig/daily driver?
