It is entirely possible that I am wrong on this BUT I am not a novice at all.
The DESIRED compression readings should be in the 125 to 135 psi range.
The readings you are posting are WAY TOO HIGH. They are APPROACHING (but not quite there) what you would expect to see in a diesel engine.
Diesel engines work without spark. They just compress the fuel with high pressure until it explodes.
The largest component in high readings like yours is the camshaft timing. I would say that it does not have enough overlap, i.e., the intake and exhaust open at the same time to permit the compression to bleed out.
All that you are going to get with those numbers that you have is an engine that can not run on pump gas as we know it and an engine that is difficult to turn over hot on a restart.
As I said, I may be completely wrong here on this but I don't think so. I've gone through this so much more then just a few times myself.
In any case, that engine is showing good compression and more then likely could use a nice "valve job" and new valve train components and those procedures will balance out the compression to a great deal.
