The valve cover look gets close. Valves close and the mark on damper will be about 180* away. I say about because there is cam lobe variations. With all spark plugs out rotate crank by hand and have a wire or something in number 1 cylinder. Slowly crank it up till the wire is not pushed out any further, this should be close
Ayuh,..... And both valves are closed,....

Not being flipped just making sure. Do you know how to use the stop bolt?

Is this correct?
Bring #1 to the compression stroke, screw the stop in and move by hand until it stops, mark it. Turn it counter clockwise until it stops, mark it. TDC should be between those two marks?
