Darren,

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.
 
Thank you very much sir! I have a 360/408 with the Eddy heads and the aforementioned kit. I used the moly ARP provided so 88-90 ft.lbs. it is.
Thanks a million!

remember - torque in at least 3 step stages to the final 90#
 
Go to the ARP web site and look up the bolts, most of their HQ bolts require cycleing or prestressing before you get to final tork.
