Put a straightedge between the center holes of the cam and crankshaft, and turn the crank until the dots align. It looks like the cam is timed properly, but I agree completely about using an aluminum gear, NOT fiber! There might be a U/C mark on the flywheel that will align with the pointer when the #1 and #6 pistons are both at TDC.
