71 demon 340 tips?

I got the engine torn down for inspection and found the whole engine appears to have been re-built at some point in time, not really what I was told but figure it is par for the course. The original heads appear to have been replaced by some 273/318 heads, a little disappointed at that, the block seems to be correct date code etc, correct crank too. The crank is .010 on the mains but oddly enough standard on the rods, which I think will work out as the rod journals should be turned to .010 to clean them up as needed. The whole thing (minus heads) seems to be painted orange from the factory (heads were blue). Only problem now is that one piston is still stuck in one of the cylinders, been soaking it hoping to dislodge it without completely destroying it. Now standard practice would be to just overbore it .030, and my cheap *** is thinking re-ring it. I want to keep the 10.5 to 1 ratio (approximately) the same and (I guess) was hoping to find some nice maybe .010 over slugs to keep as much life in this thing as possible (any recommendations here?). I already have a set of 1975 360 heads that are rebuilt and, shy of paint ready, to bolt on. So that said, it's a matter of selecting the cam and lifters. I have a set of headers already, and mufflers and pipe to run 2-1/2 out the back with a crossover of course. Now I have a tendency to over cam motors, but I usually lighten them up and gear them for it, not this time though. It'll be the stock 3.23's and full interior with the 4 speed, so I'm looking for recommendations for a cam. Hydraulic (non-roller) recommendations here please. I'll take some pics and post them later today. Thanks!
