What I was trying to say is that there's a lot more to rebuilding an engine than the parts you mentioned. I wouldn't consider an H/C/I swap as a rebuild. Rebuild normally means main bearings, connecting rods, pistons/piston rings, boring the block, etc. etc. There are a lot of parts to buy and a lot of things to consider when rebuilding - you need to be more specific about your plans and people can help you better.
