Whats torq spec for 500 efi headers bolt?
 

There must be one, not just guts feeling torq, right?

My hands are calibrated for 25-30ft/lbs. And that's what it feels like to me :)
If you get no real answer, I'd go with 25ft/lbs.

Short header bolts 30
longer aluminum or iron manifolds 25
im saying. Short 1 1/4. Bolts are 30. Longer than that are 25

goodentite,german torque.

Tight as u can get it . Within reason naturaly Then get it hot and tighten it again. And recheck in a few hr. Worked for me for 30 years.

Thank you guys! Im about ut to drop the first of the three back in!!!

That's a lot of header bolts to keep after
