I'm real happy with Percy's dead soft aluminum ones also. There is a new company just getting started, I talked with one of their reps at a drag racing show a couple weeks back. The name is Flatout Gaskets, you can check them out at www.FlatoutGroup.com. I plan on trying them if I ever need another set for my car. Keep in mind that no matter what gaskets you get you have to run them through at least 3 heat cycles with re-tightening after each cool down to make them last.

I am using fel-pro right now but if I had to do it again I would use these, you would need port size. Check these out.

I talked to the rep at Flatout and they recomended to stay away from the aluminum ones and stick with the copper with the rubber coating. I think I will go with that one #7067C

A little off topic, but relevant at the same time... Anyone ever get their header flanges ground for flatness? Seems my EM headers go through a lot of gaskets, even with proper torquing/retorquing sequences. I've had better luck with the Felpro 1406, but still can't get a good seal (can see where exhaust has escaped).
