Head Torque Specs?
Building a 350:
Edelbrock aluminum e-tec 200 heads
fel pro gaskets
ARP bolts
What torque spec do I use?
The head and gasket 'instructions' say nothing.
The ARP bolts have instructions...that are confusing and contradictory. They say to use ARP moly, no other moly, and to torque to 65 ft lbs, but with alum heads, to torque to 60.
If using motor oil on the threads, then torque to 85 ft lbs. No mention of aluminum heads here...so stick with 85, do 65 or ??
HELP!
Chris

It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.
