How to adjust roller rockers w/ hydraulic cam. First start up.

I used FO and compression got worse. I used 1/2 turn for pre-load. On zeroing, I tightened until the pushrod didn't spin.
It bothers me that my # 1 wire is on the back of the distributor. My book diagram shows it in the front. Could my wiring be scrrewed up?. It seemed to be the only way the distributor would go in with the vacuum advance pointing left (passenger side) . For the early v-8 guys, where is your #1 spark plug wire positioned on the distributor?
I am going to use the chart and see what happens. Turning 90* is more precise, but setting #2 when you're on #1? I don't understand, but will try it.

Distributor cap vs rotor position does not matter one bit. As long as the rotor points at the #1 wire when #1 cylinder is at TDC of compression stroke (or about), and the firing order is correct, it does not matter. Also where the vacuum can doesn't matter either, as long as the distributor has room to rotate enough to set the ignition timing.
