Header Bolt Torque/Sequence

[Jeff Kleiner]

I will generally start at the center then work outward alternating back and forth. You're going to find it impossible to get a torque wrench on them so just try to give them all a consistent "oomph" (that is a well know engineering spec). You need to go back through and snug them after a couple of heat cycles and if you're using locking bolts don't engage them until you've done so.

the oomph is properly attained with a wrench that measures about 6 to 8 inches, not your 14" 1/2 in drive pry bar

That’s what she said.

Sorry, could not - not swing at that slow pitch.
