Cam break-in Questions.... On an engine run stand

I am getting close to the break in time. I hope that I have all the boxes checked. The setup is not mopar factory stuff. The distributor is a "ready to run" that does not need a separate ignition module. The alternator is internally regulated and has a sense wire that goes to the starter relay. Coil is HEI hyperspark. The run stand has oil pressure, water temp and tachometer on the dash. Any other help, let me know

1. I have done the priming and will redo that before distributor install.
2. full battery, assembly lube, penn break in oil
3. Will set timing to 10* btdc before start up
4. Will get the fuel into carb and primed for start
5. timing light ready for 3500 set to 36* . then back down the rpm to 2000 for 20 minutes.
6. Transmission line connected together, fluid level will be monitored
7. shop fan ready to blow air on the radiator and water ready to carefully mist the radiator if need be.
8. Inner valve springs have been removed , valves adjusted.
9. The spark plug wires will be adjusted and placed in guides to keep them organized and prevent cross current58639958061__180DABC0-0449-4E1D-908A-042A07AF3841.jpg 58639953624__8C0140CF-1C6D-4957-99D9-CE7DADB9D767.jpg 58639955639__0D5794B8-C42E-4962-A13B-B4831C0360A0.jpg
Some questions.
When using a drill to check oil, I got 80 psi on the gauge, Ok or not, I have the high volume melling pump
I have seen some vary the rpm from 2000 to 2500 or so varying slowly, yes or no?
Should I remove the carb vacuum lines to the distributor and plug them?
How much fuel will be used in 20 minutes or so? I want to have enough on hand. 91 octane premium
Thermostat is 180*, OKAY?
Any other tips and advice, Please
