Can you port Edelcrock's TES headers where it hooks to your heads? I can get some TES headers from a friend that is selling them for cheep and has only been on his car for only a few days. He has ported them and said that he has seen it happen once on hotrod TV or something like that and I was wondering if it was really ok to port the headers?

Yes you can do that. Edelbrock left some nasty looking welds so they need some cleaning up. I was going to do this to mine but was in such a rush to get them on, I never did. Guy I talked to said you can pick up around 5 hp by cleaning that area up some.

I've done that to my headers and u will notice and increase in hp

wow i am going to get them

The AIR tubes stick down inside the ports right at the entrance. You might want to grind them out as well as cleaning up the inside welds.

Edelcrock's headers need a lot of cleaning up, porting, and help.
