What should I put on header bolts before I put them in? Last time around I put nothing and after about 750mi they are loose again. I was told by a buddies dad to put locking header bolts but 1. I'm not wasting my time on spending $$$ on a 3.4. 2. I don't even know if they make them. 3. I heard most of the time those locking bolts don't work anyways.
