What I would do (cheap method):
Inspect the apex seals to make sure that they are intact and moving freely against their springs. You can do this through the exhaust ports, and use an unsharpened pencil or something like that to push on them so you don't damage them. If you find any that are sticking, then try some Seafoam to get them moving again.
Once that is verified, then the only real risk beyond that is whether the coolant seals and oil control rings are deteriorated. Coolant seals can be "repaired" by using Alumaseal in the coolant (worked for me), and bad oil control rings can sometimes be "gotten by with" if you use Lucas in the oil.
