I'm a bit of a numpty, and misplaced my spec sheet... does anyone recall what the final torque spec is for the Carpenter head bolts?
 
Yes, they are aftermarket bolts sourced from ARP for Carpenter Racing. They are a custom offering in length for certain... I cannot speculate on the alloy, other than it is a chromoly alloy of some sort... given the research involved I wouldn't try an off the shelf item as a substitute for the bolts directly from them.

I called and got the numbers; I'll post them here as a reference.

3-step torque in factory sequence:
1) 20ft/lb
2) 40 ft/lb
3) 65 ft/lb
