Headers with offset bolt holes?
Trying to identify some headers that were given to me when I bought a used engine for core purposes. Exhaust port spacing is 4.5". The bolts are offset high and low on either side of the port, with the bolt closest to the front of the engine being low and the other being high on each cylinder. Does anyone have a clue as to what engine this might fit, or if it even sounds like a Ford application? They are for a V-8 engine, and the ports seem to be larger than the smallblock headers that I have seen.

Armed with that information, I did some research. You are right, they are 351M 400 headers. Too bad they dont fit anything that I have. Thanks, Michael
