Is it necessary to use a sealer on a composition head gasket? Such as hi-temp silver paint or copper spray on? Here is the one that is in my re-build kit head gasket (http://store.summitracing.com/partdetail.asp?part=FEL%2D8180PT%2D2&FROM=MG) Thanks for the replies, Dave.

Never use anything on composite head gaskets. It is the number one cause of failure according to Victor gaskets.

Thank You, that's what I figured. Just wanted to make sure.
