HELP! I bought a mess?

Ok so more trouble than likely worth in machine work. So what I am getting from the group for options is:
1) Rebuild the combo I have on the 273
2) Find an older 360 short block and rebuild it with the top end I have for the better heads and adjustable rockers
3) Get a reman magnum long block, do the conversion, and sell what I can that is worth something off of the engine that is currently in the car to recoup some of my cash
no matter what direction you go it will be "work" and some $$. You could go magnum heads on the magnum. I dont' know what they get to drill the block for oiling LA heads. Can't imagine it would break the bank.
