If it will clean up with a hone then run it. What are you questioning about parts exactly?

So as the title show, I just last weekend tore heart out of my baby, it ran fine it just smoked. It was bought 20 years ago rebuilt and has only had 2000 miles since then and started somewhat frequently. Well Anyways.. its a 2 bolt main, it has one slightly bent valve or just the seat, it has been bored over .060 so its been thru hell, and there Is very few vertical lines in the cylinders.. but I took the bottom end out too. Now I need to know all of your opinions on my block, but id really rather keep it I don't really plan to make a HP monster or anything. But my biggest questions come around the time im looking at parts to order! I plan on re honing it, rings, bottom end seals, and then all the gaskets. Any suggestions???
First off, depending how long the motor sat/mileage/etc and what cam you choose will determine if you need new springs or not. Old springs get weak over time, especially when not cycled.
New cam = new lifters (unless it is a roller setup in which case you can usually re-use what you have). Do NOT order bearings until you measure everything and know exactly what you need.

Yeah the cam I order came with lifters, its an edelbrock street/strip not sure of a part number off hand, and i'll probably just take the bearings into the parts store and have them decide what's needed
Pretty much... the crank/rod journals need to be measured, and it's best a machine shop check the cylinders both for thickness and straightness. My cousin had a +.060 400 some 10-15 years ago and lost the engine thanks to a chunk coming off the top of the cylinder right at the deck... cylinder walls were too thin.
