about to start doing a gasket swap on hooker long tubes on lt1. should i put a dot of lock tight on the bolts or leave them bare if i should use lock tight which one blue right????

 

Just use anti-seize on the bolts. Don't use locktite, just make sure they are tight, and re-tighten them after some heat cycles. Mine never loosened up even after a few heat cycles, don't understand how so many people have problems with header bolts coming loose.

 

mine cam loose a little but i always checked them but since i am putting on the new gaskets and it is such a pain in the a$$ just tryingt o make it where i dont blow out another set and have to do it again

 

I agree with the post above, use a small amount of antiseize as your threading steel bolts into an aluminum head. Loctite won't work anyways as the heat of the exhaust would "melt" the loctite.

 

You'll just have to periodically check them if you are worried about them loosening up. Or just opt for a set of locking header bolts.
