Torqueing heads

Post by coop »

This site is awesome, I am going to be reinstalling my heads on the 70 F250 w/390. I have found the sequence and the torques for the heads 70, 80, then 90 ft.bs. Should you snug all the bolts up before going to the first 70lbs or just start out in sequence from bolt 1 too 10 ? I have cleaned the bolts and threads in the block I saw somewhere on another thread to put moly grease on the bolt threads? Or should they be left dry? I want to get this right the first time. Again thanks for everyones help. :hmm: :fr:

Light coating of oil on the threads and around the bolt head or bolt hole on the head, not too much though.

Thanks Bobby, what do you think about bringing the torques up should they be snugged before going to the first 70 lbs or does it matter?

Run all the bolts down until they're "snug", then get the torque wrench. Remember, smooth pull on the torque wrench. When asembling, i always make one last pass, after everything has been torqued down, just to make sure.

Snug them. In fact I snug them to about 20 before I start torquing.

:yt: I usually snug them to 25-30 ftlbs just to get them halfway to the first mark. It doesn't hurt anything to be cautious!!! :2cents:
