For quite a while I was running the cheap paper gaskets that came with my BBK longtubes, but last week a couple of bolts worked themselves loose and I blew out the driver side gasket (moral of story: check bolts periodically, I had four total between both sides that were visibly backed out, and one was missing altogether).
Today I installed a multi-layer "dead soft" aluminum gasket from Schucks, and it immediately leaked badly. It seems like the holes in the gasket are too low, and it doesn't leave enough material overlap on the top of the exhaust ports to seal properly. So I picked up a set of Mr. Gasket copper gaskets, and installed one this afternoon. I've got it damn tight, and still it leaks a bit. Not as bad as the aluminum, but it's audible.
So what is everyone here using? Cheap gaskets? Permatex copper? What???
At this point I'm either going to order a set of Fel-pro 1415's (couldn't find any parts store today that had them in stock), or I'll call up BBK and request a set of their cheapo paper gaskets. At least those didn't leak...
