OK. I have a 350 with the vortec heads, and an Edelebrock Performer manifold, my problem is That I used The regular fel-pro manifold seals, and I'm getting Oil leakage right in the middle of the manifold, where the heat crossover is.

Does any one know of a better seal for alum. manifold to Iron Heads? I've heard that they make some that are thicker for that purpose, but do they work?

Also my oil pump is capible of 80psi @4000 rpm, so could that be a probem? i would apprecaite the help.......
