I'm getting ready to put a 300-6 in my 78 Bronco, I know that the Bronco is the same as a F-150 as far as frame, firerwall, and evey thing else in the engine bay. I found a set of Headman headers, Hedman Hedders 89300 - Hedman Street Hedders - Overview - SummitRacing.com but they will only fit 2wd but look like they would work, I also found a set of hookers headers, Hooker Headers 6823HKR - Hooker Super Competition Headers - Overview - SummitRacing.com thease fit a 4wd but cost way more money than I have, yet look similar. My question is if any one has tryed to use the headman's on a 4wd, and do you think they will work? I can modify them if I have to but don't want to fully build new headers out of them.
