Checking cam lobes and lifters on a pre-buy

[ualdriver]

Messed up my first post on the forum and it deleted. Oops.

I'm looking at buying an airplane in the up and coming months. Two of the aircraft that I am currently looking at live in Florida and don't fly much- maybe a few hours per month. I'm concerned about corrosion, not so much on the fuselage or even in the cylinders as if it is there, I think it will be found by an A&P during a pre-buy. I am more concerned about the internal portion of the engine, in particular the camshaft, its lobes, and the lifters.

Is it a big job for an A&P, during a pre-buy, to examine the engine's (Continental O-360-es) camshaft, lobes, and lifters? Is it even possible? Does it make sense to even do such an inspection?
