Cam break in during cold weather?

how would I check initial timing sense the motor will be at rpm and be advanced from mechanical/ vacuum advance. what should timing be when im sitting at 2200- 2500
Prime the engine with a drill. Verify that you have fuel and spark. Fill the carb bowls so you’re not cranking on it all day. Verify you have spark.
Disconnect any vacuum advance. You won’t want it during break in. Turn the engine over by hand with the driver side valve cover off. Once the number 1 intake valve closes, keep turning until the damper timing mark is around 20 btdc. Once that’s set, install the distributor so that the rotor is pointing directly at the #1 wire on the cap. It’ll fire and run on the first revolution. All of this is way more important than what weight oil is in it.

Verify the firing order as well.
