I think it will be best to static time it to start it. You will get close enough to start it, by setting the crank at about 10 degrees BTDC at #1, and a reluctor tooth on the pickup. Then check where the rotor aims, and use that for #1. To check engine phase for sure, pop valve cover and see that #1 valves are both closed. Use timing light to adjust timing, when running.
I think you may find your engine running much better.
