Hi. I've decided my 1961 Monterey with the 352 is finally going to get it's cracked pass. side exhaust manifold replaced. I find manifolds online that supposedly will fit my car...and other early 60's/late 50's applications, but none of them have the same casting number as mine. My current (cracked manifold) casting number is 5751204, which doesn't seem to fit the typical Ford numbering scheme ("C" prefix, etc.)

-How much should I pay attention to the casting number?

-Are all pass. side manifolds for 352's from that era going to fit my car?

-My current unit has a heat actuated flapper valve. One of the used ones I'm looking at doesn't have a flapper valve. Would that be a problem using a manifold without a flapper valve on my car?
