Slade, as noted in other peoples posts, each piston reaches TDC twice for one single rotation of the cam(s). This is a 4 stroke engine. So every other (say even) crank/flywheel rev. the cam marks will line up and every other (say odd) flywheel rev. they will be 180* out. Put another way, the cams turn at half crank speed. So it sounds like your cams are fine. FYI if any valve tries to fully open while its' piston is at TDC that valve will be bent. Also, don't ever turn the engine by levering on a camshaft. Cheers.
