    Is there any differences for any 350 exhaust manifolds? Like is there a different manifold for a single exhaust versus dual or better flow for certain years?

    Im pretty sure they're all the same as far as runners, the only difference might be the cars with the heat riser valve on the drivers side, IIRC, engines with that style manifold, the flange is flat verses tapered, the taper is on the heat riser valve.

    the Apollo driver side is different in order to clear steering box .
