Early A Body Fenderwell Headers

The next motor's gonna be too radical for that small of a header. 1 5/8 primaries & only a 2 1/2 inch collectors would be fine if I kept the stock 360 Magnum to get it rolling. HOWEVER, I called Hedman yesterday & they said they would build them for a standard flange. Gonna call again today to see if I can get W/2 flanges for extra cost. 2nd motor's gonna have pretty well prepared LA-X heads,11.5-12:5 compression (360-1s slated to go on as an upgrade) big Hughes solid lifter & some other tricks. Object of the Valiant is to use my radical small block stuff & tame down my '69 'Cuda A57 car I'm building.
BTW, the headers have 1 7/8 primaries & a 3 1/2 collectors.
