Quote: I have an Eddy headed 318 with the 340 Hi-po exhaust manifolds. The bolts loosen every time I drive it. Is it Ok to use Lock-Tite for this application? That's the only solution I can think of to solve the problem.
I use Permatex anti-seize lubricant #133K on my aluminum heads. You might also want to check your exhaust hangers and make sure the exhaust system isn't flopping around.
