Default Gaskets for my headers?

What gaskets do you use for long tube headers? I have EM long tubes on my LT4, and the Fel Pros seem like they come into the ports a little.

By "come into the ports", do you mean the gasket is smaller than the opening? Is that on the headers, the heads, or both? If they're not smaller than both, they'll work fine. If they are, Fel Pro offers a variety of sizes, as do others.

RACE ON!!!

I'm using Felpro 1406 header gaskets with my EM longtubes.

Whoops, i guess i mean both heads and headers. I will try the Felpro 1406s if i can get them at the parts store today. With the work on the intake and heads, the gasket seems a little small, i had to trim it into the blue sealing ring around the ports a little. I wasn't aware i could get a larger size. I iwll see what i can do.
