I would go through it completely, if there is copper showing it was likely run hard to get that much wear. Plus you would have a known starting point with the internals as you can flush out the block, check the bores for wear and at a minimum replace the bearings and rings with a light hone of the bores. Then go over the heads the same way, clean them, and at a minimum new stem seals and lap the valves to see what the seats look like. It won't be a new engine but refreshed enough that it should run well and give dependable service.
Good luck with it. Those are a nice car to make a cruiser out of.
