Number 1 piston at the top of the stroke with the valves shut on the head for that cylinder. Install the cam sprocket onto the cam to get the alignment marks exactly where they need to be. As long as the number 1 piston is at T.D.C. you will be fine. To be safe rotate the crankshaft counterclockwise a few inches so that all of the pistons are in the middle of the stroke and install the head. After you are sure the cams are set to the correct position rotate the crank back up to T.D.C. turning it clockwise and install the belt. This will not work for chain driven engines but should help calm your nerves. Hope this helps.
