No idea what stamping numbers mean. What is the casting number and the valve size?

They are 915 cast # with 2.08/ 1.74 valves.
The letters stamped are H and P.

Some people like the uniqueness of the different "correct" stampings. It is part of the fun and challenge of restoring these cars, to find the parts that the cars were "born" with. Take them back to how they were in the old days, before some of us were driving. Kind of experience a different time. Saving the Mopars. Its not about how fast you can make them, anymore. Just my opinion.
