    I know MAC makes headers that supposedly work, however personally, I wont use any of their reverse engineered Chinese crap on anything I own.
    I have heard you can use BBK, but spark plug access suffers.

    The regular unequal MAC shorty headers will work with 90* boots. I had them on my GT40p heads before I got the Ford Racing shorty headers. I think most of the long tube headers will work. Are you wanting short style or long tube?

    have you looked in the ports on a set of bbk headers? here is what my cylinder heads had to try to breather through on my bbk longtubes:

    Curious about these MAC headers...I see they're for the SN95 5.0s, but maybe?
