I was wandering if a 13b header will fit on a 12a???

well, im taking a shot in the dark here, but i would guess since the turbo2 manifolds can fit with ovaling out the holes, i dont see why you wouldnt be able to oval them out on a header. i would still probably rather have a header made for that engine. the 12a is 10mm shorter than the 13b.

im sure someone with more experience, or that has tried it can speak up.

You can cut the middle part of the flange out and make it fit the 12a.
