Whats everyone using for header gaskets? Everything I look at fits the inside holes and the supplied headers are using the outside holes. And I had to grind the crap out of the flange so the spark plug boots would go on the plugs :(
Here are 3" bolt spacing gaskets. Fel-Pro 1487 or Remflex 3039, Remflex 3035?
I stayed away from the Remflex as they pushed the headers out far enough to concern me with spacing between the header pipes and footboxes. I went with standard Felpro gaskets. Headers aren't that hard to seal properly so a regular gasket should work fine.

Aaron, what did you use on sidepipe flanges?

I got the 1487 ordered. Thanks :) Good question on the flanges?
The Remflex 8065 has been used quite often on the side pipe flange here. 2" openings with the 4-3/8" bolt pattern for the flanges.
