Hedman Fenderwells w/ RB motor...

I don't know how 'set" you are on fenderwell headers. But i will relate my experience with BB A-body headers i have used. I just don't care for either brand of fenderwell headers and have ran both Hedman and Hookers. My header of choice, especially big tube are the Pro-Parts formally Herb McCandless design. They have one tube on the on the pass. side thatruns outside the framerail and two on the DS. I have used these on Low decks and RB's Easy to take on and off. I hope this helps.
