Turn the crankshaft to TDC, then 90 degrees more (either direction) so the pistons are out of the way. Then turn the camshaft so both cam lobes on #1 cylinder are pointing up. If there is any resistance when you're turning the crankshaft you may have to turn it counterclockwise 360 degrees so you keep from hitting the valves. Just take your time, it may take some combinations of rotations to get the camshaft and crankshaft into the right position at the same time.
