You are correct for alum heads.65-70 for iron. The bolts hooking the stands together are 12 lbs, and the adjuster nuts are 25 lbs. Watch that the rockers line up straight with the valves. On my dart 360s I had to put a .030 shim between the stands to kick 8 of the valves over to line up straight. If this is the 1st time, make sure the stands dont sit on top of the head studs, a few of mine did and had to cut the top of the stud down. Good Luck,TC This is a BB?
