What did you guys torque your ARP main studs to in RB30's?
Factory spec is 54 Nm
I just received my set and the paper says the set is for some subaru engine head studs. 90ft/p or 120Nm is the torque spec for them. Does this sound right for main studs in an RB30?

I put the kit number into that link last night came up with 90ft/lbs, the kit instructions say the studs are for some subaru engine. Just seems like alot of torque for main studs.

Has any one assembled their motor and held down their main cradle with 90ft/lbs and arp studs?

Christ this is going back a while. But from memory the last tension was 120ft/lbs with a ACL multi layered steel head gasket.

I sent a message to my engine builder, hopefully he gets back to me soon.

Thanks for your help guys, I went through the part numbers for RB series ARP main studs and found part number 202-5406. It has the instructions for RB series main studs (200,000psi 10mm dia) and says to torque to 60ft/lbs.
