I too am anxious to hear if the headers make a big difference. I installed the progressive 2 barrel from Tom's site and it really helped the Carryall on climbing hills on the highway. I'm running a 251 with a stock cam, exhaust manifold and single exhaust, it sounds good. Did you go with a different cam and 2 barrel carb?
