adjusting the timing???

I have searched and read how to adjust the timing on here for days and I cant get a clear answer on how to plug the vac line. Please correct me if im wrong.
Warm the engine up, unplug the vac line from the dist and plug it. So, do you leave the dist vac port open??? Or plug it to. Basicly, do you plug the port on the dist, or leave it open and plug the vac line going to the carb?

Also, everyone says something differnt on engine speed, 650,750, 850, or 1600 rpms. What actuall RPMs do I need to set it at?? The engine is an 1988 258 with 170K on it, team rushed, nuttered, 32/36 Weber, and holley Fuel pressured.

Plug it at the advance. Set it at 1600 rpm.

Plug the vacuum hose that runs back to the carb. I use a golf tee. The port on the vacuum advance at the distributor can be left unplugged because it creates no vacuum.

When Nuttered, timing is adjusted at idle speed (650 - 700). This is the way I do it and have had no issues. And I've played with the timing a lot to find that perfect spot.

If not Nuttered then it has to be timed at 1600 RPM along with disconnecting a few things (I don't remember what they were).

And at 1600 RPM the weights should be starting to move out. At idle the weights aren't out yet. So you can time it at 1600 or idle.
