RE: touqe specs?
are they pedestal mount or stud? the stud mounts you adjust them with the lifter at the bottom of the bore. you turn the push rod while tightning up the adjusting nut when you can turn it easy anymore you turn 3/4 of a turn with a wrench and lock the jamb nut down

Yes, sorry about that!
Use the proper torque sequence for the heads when installing them.
If your looking down at the top of the head here is the torque sequence order:
Inside of the head (intake side)
9 5 1 3 7
10 6 2 4 8
Spark plug side
This is the tightening procedure I used on my AFR heads:
Top bolts: 30lbs, 50lbs, 70lbs, 80lbs
Bottom bolts: 30lbs, 50lbs, 70lbs, 75lbs
Need anymore help?
