I have BBK unequals and I have previously blown the paper gaskets. I now have decided to try out the copper ones since they will not blow out. Well I really cant get the old paper gasket off so my copper gasket leaks pretty good making itself really annoying. So what do you adivse I use to make a seal that doesnt leak? Header Sealent? Will that stuff work? HELP!!!

Parts in the basement : To much to list. heres a hint..it involves a watts link and turbos.
Ace hardware sells this stuff called Tough Job Remover. It took the powder off an upper intake like magic. Your gasket doesnt stand a chance. A razor doesnt affect it?

This is a bad thing to do. I've seen people really screw up a set of headers and/or heads. They have sanded too hard in one or two areas making an un-even surface making it harder then before to seal things up

copper head gaskets - heard bad things - never experienced tho - i've been using the old school fel-pro gasket just fine, no leaks, im using locking header bolts from stage 8 .

If the flange is clean and in good shape, a metal type gasket, especially at the collector, will seal and will not blow out. That is their greatest advantage.
Copper Header Gaskets. How to make them not leak?
