I have a 440 that runs about 200psi. Compression check numbers are Highly dependent on the cam’s intake closing degree. Early will produce BIG numbers.

I agree with others about cleaning the engine (water, sea foam, etc) then a retest. I’ve seen some pretty significant shifts in the numbers after doing that.
But in the big picture I wouldnt let those numbers themselves to cause me to do anything to the motor if it’s not consuming oil, other than the aforementioned cleaning. Those numbers aren’t costing you any big amount of power....at all. Have you playing with the timing for the pinging issue?
