I am looking for thoughts on BBC intake manifold bolt tightening.
I have a 540 BBC with Dart Pro 1 heads and run a blower using a INDY Cylinder blower manifold. My question is how much torque is needed for the bolts that hold the manifold to the heads. The Dart instructions recommend 35 Ft. lbs. of torque for the intake manifold. My issue is that I use stainless steel socket head cap screw bolts to prevent rusty bolts, however the maximum recommended torque for stainless socket head 3/8-16 bolts is 20 Ft. lb. What are the thoughts of the experts? Is 20 Ft. lbs. enough?
