This is my first RC so I'm new to the club. It's a 84 4x4 Prospector with a 318 in it. It had been sitting for a while, so I'm changing all the fluids and giving it a tune up. It runs pretty good, but it is a little cold nature. Has a little hesitation until it gets good and warm. But I found a pair of these headers at a GREAT price. Any comments would be great on these headers. Anyone run Hedman headers on theirs?
