Ok, refresh my memory here, but I thought TDC for #1 (compression)you can set both intake and exhaust for #1?? Then rotate crank 90* and set #8 (intake and exhaust), turn another 90* then set 4 intake and exhaust?? The chart above looks different?? Also when you say backside of the cam, you mean on the downside of the cam lobe correct??
