What’s the best way to purge air from cooling system I flushed heater core still heat gets cool at idle I tried the 3500 rpm thing about 5 times still cool at idle I could use some help

Welcome to this forum! Run the heat with the engine on, and the radiator cap off for a few minutes.

It helps to have the front higher than the rear. Park it facing up hill. My V8 is pretty easy to burp - no real gotchas like on some other vehicles. If your heat still isn't working correctly then check the heater control valve.

Park it with front uphill, remove cap, squeeze upper radiator hose with both hands several times until the bubbles stop. You can also squeeze the heater hoses. It helps push the air out of the system.
