I got my manifold from Clifford but it has no name on it. I heard at that time the mid '70s, that they were going through some changes and that Offenhauser was doing their manifolds. Mine was cast for exhaust heat from a stock manifold so they sent a plate that didn't fit. I returned it and they welded the plate on and sent it to me. Not a lot of choices back then for GMC stuff especially a GMC 4bbl intake. I thought it would be cool but I was wrong.
