Tearing Down Unknown 360

I'm tearing down the motor that came in this truck that I bought back in the early summer: http://www.forabodiesonly.com/mopar/showthread.php?t=62220
My plan is to freshen it with rings and bearings (if all is well inside) and put it in my 74 Dart Sport-gonna-be-a-71 Duster project. It ran good.

This is what I've found so far: The 915's are ported, have 2.02 intakes,
Crane Gold Rollers, big valve springs and retainers (unknown). I haven't removed any valves yet. There is a "J" cast on the bottom. Disregarding the unknown value of the porting work, are these good heads?

It has a stock crank, stock rods (.010/.010). I've only looked at a couple bearings, they don't look too bad. I'm going to plastigauge them. The rods have been ground for balancing (7 of them), and it has a windage tray. I haven't looked in the oil pump yet. The pistons appear to be .030 KB190's. (10.5:1) They have the shorter quench dome of the two part numbers I found. I don't have them out yet, but there is no ridge, and I can see cross hatch. I'm going to cc the heads, check the deck height (Do I measure around the edge, not on the dome? Never checked any except flattops.), the gaskets were FelPro blue. I want to figure the comp ratio and see if I can get more by cutting the heads, or block, or both. I'll check piston to valve and cut the pushrods.

It has a double roller chain and the cam appears to be a .509 purple shaft. The lift at the lobes X 1.5 = between .507 and .513. It has purple paint between the front two journals. The numbers 970406 on the back end of it, if that helps. Is this a purple shaft? I know there are better cams, but I have it and plan on someday, building a 408, so it'll do for now.

If I can run this with just bearings, rings, gaskets and some decking, that'd be great. Thoughts?
