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.

It's a 60 year old Pontiac V-8 with 150K on the clock. It is worn. Worn out is in the eye of the beholder. It comes down to your personal goals. If you want a leak free, dependable driver to cruise around in on the weekends, I would remove the engine, clean it up and reseal the entire thing with a gasket set. The end result would be a reliable cruiser making 275-maybe 300 HP tops but would run just fine. Could probably accomplish this for $300-400. To do a proper rebuild, replacing all the parts to blueprint it properly back to like new condition would run 5-7 K to have it done by someone who knows what they are doing. The result would be the same engine making 340-375 HP using all stock castings and modern pistons and rings.
If you live in the Dayton, OH area and I think you do, shoot me a PM for an intriguing option where you can build it yourself for free, (labor), and have a great engine fresh off the dyno when finished. (assuming your over 55 years old).
