If your planning on doing a complete rebuild, then sometimes it's only a few dollars more to replace the whole thing. If your doing it right and doing the rebuild yourself, then you need to have a quality master rebuild kit. You will also need to tear it down, have the block and head vatted(cleaned), have the head magnafluxed and check the deck clearence, have the block magnufluxed, have the rods removed from the pistons (not something most people are equipped for), have the rods checked for warping, cracked, or out of spec or replace them, have the rods pressed to the new pistons. None of this is something you can do unless you have access to a machine shop and know how to use it. You also need to have the crank turned and either hone the block yourself, or have it bored. Thats all machine work you have to pay for. Not counting the price of the rebuild kit and your time. Remember also when you do the rod and main bearings they need to be done twice, 1st time with plasti guage, then removed and checked for specs, then if it's all good you have to tighten it all back again. Like I said, on most of the engines I deal with, it cost me about 50-75 more to get one from them. My time building an engine is certainly worth more than 50-75 dollars. I found out working in mechanics a long time ago, to do it right and with quality parts, it's not much cheaper than paying someone else to do it and having a warranty.
Not saying anything bad about just fixing whats wrong with it, but with the damage you did, you need to overhaul the entire engine, not just a few rods and a piston. You also need to have a machine shop check for any other damages.
