    Header Help 1980 Trans Am?

    I have a 1980 Trans Am with a 71 GTO Ram Air IV 400 and Muncie 4 speed. I am looking for a set of long tube headers to fit Ram Air IV cylinder heads and clear the z-bar for the Muncie. Ideally, a round port ceramic-coated header; if not, I'll have to go with the exhaust manifolds. Thanks in...
