RE: exhaust leak
hmmm..a performance 2-bolt gasket seems to be more illusive.
so far ive only found fel-pro...
2 bbl-FEL-PRO Part # 9547
4 bbl-FEL-PRO Part # 60025
but these are NOT full copper gaskets.
a few more questions, is it burning them on both sides (both manifolds), or just one?
Another thing, are you certain that they are tight enough? I have seen cases where the aftermarket gasket surfaces were thinner than original, and the studs/bolts and nuts were made to be tightened to a certain point, and when tightened down, they were bottoming out and not getting a good seal. Also, if you are tightening them TOO much, and you are crushing the gasket, it could also create a weak point.
When you put the gaskets in, have you tried putting a thin bead of silicone "gasket in a can" around both sides first?
