Since I had little to do this afternoon, I went through all of my documentation to see what the factory maximum oil pressure should be. I found only one source that had it, and that was a 1960 "Motor's" automobile repair manual that had entries for the '53 Ford. It lists the maximum oil pressure for a 1953 flathead was 57 psi. Interestingly, this was higher that listed for all of the later OHV engines.

It looks like 60 psi is right in the ballpark, given the possible variance in the gauge.
