I never list to see an open shortblock sit that long without being properly preserved with grease and/or assembly lube. Rotate the engine after GENEROUSLY spraying all cylinders and the crankshaft journals (main and rod) with oil (WD-40 in a pinch, but that's not really the same thing).

You're looking for any binding of the crank, any rust in the cylinders, and any grooves created by standing water in the cylinder. If any of these exist, you need a bore, polish, new bearings, new rings, & rebuild.
