Header bolt torque spec for 525?
 

What is the torque spec for 525 header bolts? Original CMI headers passed pressure test. Thx

OEM gasket will be fine at 25-30 fp... there is a reusable gasket but not sure of the spec , probably the same, might want to use some anti seize on the alum. heads

3/8ths coarse into alum heads. Stick with low side of torque spec.

Run it through two heat cycles and re-torque after cooled from each heat cycle.

SS Studs
 

A few years ago we switched to SS studs/nuts vs. using SS bolts. The studs and nuts make it much easier to get the manifolds on and off on a side by side install.

If you are going to use anti-seize. Use the copper colored for dissimilar metals. The silver stuff will screw you

Thanks for all the replies. I will keep it 30 ft lbs or less, and occasionally check the bolts. Some have to be by feel with the wrench, I'm just not that flexible with side by side engines.
