Don't buy any parts now. Take the block, head, and crankshaft to a good machine shop. They will strip it if not already done and boil the head and block to Magna-Flux for cracks. If good you can proceed to rebuild the engine with ALL new parts ( I would) and will be able to tell you what size to buy - they'll bore cylinders, size new piston and bearings, or, they will get the correct kit for you. They'll regrind the crank and dust the head if warped too. You want to do the job right the first time and not have to pull it all apart twice do you? Unless you are making this a DIY project and learning experience, a qualified shop will be able to assess everything and tell you what you'll need.
