Default Help ID Holley Power Valve

I have a Holley power valve I am trying to ID. My 4150 DP came with a 65 power valve, which I replaced with a 75 valve. On a subsequent teardown I THINK I put the original 65 back in.

My Holley book shows the numbers stamped on the flat sides of the casting, but this one has numbers on the steel plate on the back/front. There is clearly a 7 and a 5 on one side, and also a H and 6 on the other side which I believe is the date of manufacture.

Depending on how it is read, this could be a 65 valve dated H 7, or a 75 valve dated H 6.
Anybody?
TIA, Pete
