Thanks, Ed....I can't believe someone actually agrees with me on something.

The red "high temp' silicon, and the blue, and some of the others are fine for intake
manifolds and such...but the Permatex 598B is made for manifolds that usually "did"
but no longer require a gasket....which shows how tuff the material really is. I was
suprised when I got these Sanderson aluminum headers for my hot rod, and the
directions specified that the headers be installed without a gasket, using only
the598B that they called for.

You can imagine how hot these headers get. [X(]

FBD.
