Should you run a car without a thermostat?

I have 355 sure grip for gears,2.5 in exhaust,am running at 12 degrees and 34 initial,with a A833 4 speed.I meant octane boost in 91 gas.

When does it ping?? Like cruise or wide open or on a hill at part throttle or all the time?

What heads are you running? 69? Do they have new valve seats? Hell could have burnt valve seats, carbon built up in the combustion chamber too.


Can you record a video and post it here?
