Default Compression test

I was thinking of doing a compression test on my motor just for fun to see what my cranking compression is. Not having done one before I'm just wondering about the procedure. So I would pull all the plugs and probably disconnect power to the distributor (HEI), although with the wires disconnected and the plugs pulled may not need to pull the power to the HEI? Then for the fuel supply, just disconnect the fuel supply line at the pump inlet and plug it? Then the primary throttle blades need to be open?

Thanks.
