hey, this may sound dumb, but i was bored this summer and i decided to port my headers. there was no real performance reason, but i thought id ask if i gained anything? when i say port, i mean grind off the huge bead of weld that was inside and used to hook the flange to the tube. [&o](yes, i did grind through on 3 spots, but i welded it back up and ground it level.)
i cant tell. i didnt drive her for about a month, and going from my focus to the stang was a hell of a change, so i cant really tell. i was wondering if anyone would know anything about this.
you are supposed to tell us whether it did anything, not the other way around! now you gotta go get new headers and try it again since you ruined the first experiment.
