N 6027 -- MOPAR Small Block V8- Pre Magnum, 318, 340,360, 1-1/4" x 1-3/4" End Ports,2/Set

These look the closest to what I have. I've spent the past two days measuring every thing in sight but nothing on their site agreed with what I have for exhaust port opening. Thanks 440 and to the rest of you also.
