Distributor out, lost my marks

I know where the #1 post is in the cap and can mark that on to the distributor body, then remove the cap and install the rotor pointing at the mark

I can set the engine up to #1 TDC

now what I need to know is, should the #1 post be directly in the center of the rotor head?

Or should the rotor head be just about to start contacting the #1 post?

I know that I can just adjust the distributor accordingly either way as long as it's in the general region of the #1 post until I achieve the correct ignition timing with my gun,

BUT I want it to be as close as possible because I'll be firing up the motor for the first time after being torn down and the new cams need to go through the break in procedure by running the RPM at 2k (immediately) for 30 minutes. Any time idling during the break in can damage my cams

So I can't be screwing around with the timing light during the cam break in

I replaced the distributor and can't get it started. the marks I"m using for TDC are the five notches on lower pully, are those right? If not, HELP???? secondly, is it possible to set it TDC on the exhaust stroke and not the compression stroke using that. I'm frustrated.

You could remove #1 spark plug and use a plastic drinking straw to confirm your engine was at TDC for #1 and not a full crankshaft revolution "off" when the pulley marks line up. Do NOT use a pencil to do this !!!

Search Google for more information.
I actully have a tube that my dad built for a compression tester that I used to have that I can fit down to the plug hole and be able to feel pressure out the top. It doesn't screw in, but has a rubber cone that will seal the hole, I found that last night, will try today.....

Five notches on lower pulley are need the left most one for TDC.

First I would double check to make sure everything is connected (especially plug wire orientation). If the timing were that far off, I would wonder if the valves could hit the pistons even just during starting attempts, so if you arent hearing any bad noises Id start with checking connections first.

And yes, my understanding is that it is possible to end up at TDC on exhaust stroke. I actually "rented" a compression tester so I could know for sure when I was on compression stroke of cylinder 1. Since my distributor wasnt removed, I could also tell by the fact that the rotor was pointing at the #1 plug wire. Since your distrib was removed, the compression tester might be the best way.
I"m not hearing bad noises, but it seems to me that the engine timing should prevent valves hitting pistons. That hasn't been changed. Ignition timing, while it can cause problems, isn't going to effect engine timing.
Once again, mine is ignition timing, not engine timing. I got it started and that's good. it's not right, but I have plan to get it that way.....
