What is everyone's preferred header gasket for this application? port size is 2.070" x 2.070"

Thanks!

I think early ones had 4.9 bbf bore spacing and you had to cut bbc ones apart. Later ones have 4.84 bbc spacing so you can use whatever bbc header gasket you like.

Percys "Seal 4 Good" header gaskets are the best that I've found. I'm not sure of the part number for you.

That really depends upon which A460 head you have.
Different A460 heads have different exhaust port location exits.

I know I could go the silicone route, but I am so picky about cleanliness and neatness, I don’t think I would like the results, especially on a dragster where it’s right there staring you in the face! Lol…

I use it on my dragster...The trick is to use just enough and not too much..
You can't see it on mine..
