You'll want to measure valve height and properly shim the rocker that was tossed. Re-using the old shim is a bad idea considering it probably wan't the proper thickness.
As for compression loss, more than likely your piston said hello to the valve and bent it, its no longer seating properly and allowing for compression loss. As others said, get a bore scope in there and check it out before moving forward.
