Header Bolt problems....Backing out. I was wondering if I should use some kind of LOCTITE or whatever on these. They would be going into Dart Pro 1 Aluminum Heads . I also am using Ceramic Coated Headers ....(Headman). I have 3 bolts come completely out. And I try my best to keep up on the tightening of the bolts that came with the HEADERS Small 3/8' head header bolt.

Sometimes on header bolts changing from the flat washer to a high collar lockwasher, part #7204711, will resolve bolts coming loose. I would recommend a high temp silicone on threads over using loctite. The silicone will not damage threads if ever wanting to remove bolts.

This stainless bolt kit will work for the flathead Ford applications and is the same length used with our header kits.
