Verdict - 190-210 lbs across the board in all the cylinders.
That's suspiciously high for an "original" engine. Are you SURE the gauge is accurate?

Easy. You pull the heads off to re-gasket...LOOK at the bores. Either you still see hone-marks at the top of the cylinder, and no ridge...or you pull it down. You yank the pan, pull a main cap and a rod cap, and the bearings are in great condition...or you pull it down.

For that matter, a borescope might tell the tale of hone-marks, depending on the resolution of the camera and screen.
