I work at the Specialty Products Division of ARP, so I think I may be able to help you. What kit number do you have or is it for a small block or big block head? Here is what should be in range of wwhat you need:
#144-3603 (SB Chrysler w/Edelbrock Performer) est 88-90 ft-lbs w/moly
est 110-112 ft/lbs w/ oil
#145-3608 (B/RB Wedge HBK for Edelbrock head) est 58-60 ft-lbs w/ moly
est 73-75 ft-lbs w/ oil
The small block kit contains 1/2-13 bolts, while the big block contains 7/16-14 bolts. Both kits are made in 4037 material. Hope this helps.
