It sucks when people overbore engines in the beginning LOL, so they can't be rebuilt without sleeves. If you could find another block at the junkyard, I would do that. See if you could get one for like 100.00 with exchange. Looks like you allready have the intake and carb. The exhaust ports on the heads could use some porting to the roof of the ports. Thats what I had done on mine, and without headers it runs real good. How big of a cam are you looking at. I have the elgin version of the performer cam and it seams to work great. With the amount of money it looks like your going to put into this, I would look for another block. How much ridge did it have? There should be a buildup of blocks lying around with so many people putting in 460s. Also make sure it isn't allready a 400 since its been rebuilt.
