383 Build - Help!

I just moved, so I don't know anyone in the area that can help me with their brainpower. Any help is greatly appreciated.

I have assebled engines before, never a Mopar. Admittedly I am out of my element when it comes to determining what I have and what my options are.

Here is what I have:
1) 383 with new pistons, rings, bearings, cam bearings too - no idea what the pistons are
2) 915 heads, appear to be in very good condition, possibly new springs/valves, looks like they have the larger exhaust valves
3) Tunnel ram with 2 brand new 390 carbs
4) Schumacher headers
5) Water pump, oil pan, dist, valve covers, balancer, pulleys, fan, alt, fuel pump
6) 383 4 speed car with 3:23 Sure Grip, 14 inch Cragars, dual exhaust

I need:
1) Cam and lifters
2) Rocker assembly
3) Oil pump/pickup/rod
4) Head bolts
5) Clutch/pressure plate/flywheel

I've done alot of research, on a clutch, head gaskets, etc, I spoke to Comp Cams and the guy was very helpful, but since I am not sure what I have exactly, he could not recommend a cam- etc etc.

I am not sure what the pistons are. The only markings I can find are on the inside, it looks like 040.

I did not put the engine together, the plan was to check the torque on the rod and cap bolts. I would need to drill the crank for the input shaft.

Low budget, of course, and I really want to use the tunnel ram. It is on the stock 383, which is coming out.

I attached pics below- any info on how to make this work would be huge.
I realize some may say I am an idiot for this or that, and I would agree! That's why I am asking for help. I have gathered this stuff over many years for various reasons and began to think I could put something together with a little more effort.
