I timed the block last weekend, then started to rotate her to ensure everything was fine with no valve/piston issues. Now, I forget how many rotations it took, but I know someone here knows, but for X number of rations, the timing chains get off the cam/sprocket mark by 1 tooth. Just curious ... when I put the cover on, she was off by 2 teeth because I rotated her so many times to vacuum out the heads to ensure that the porting debri was all out
