1965 MOPAR, 273 Exhaust Maifolds

Your RH manifold is a '68-70 version. The '64-7 came with the stamped steel heat riser weight and have an earlier casting number 2465769 IIRC.


I got those off of some internet postings... That was what the listing said, however as we know, some listings may not be correct...

The point I was showing is the ports on the early manifolds do not overlap with the air holes on the later model heads and should seal on those also...
