As to sucking cold air back into the hot heads and warping the valve, this can happen if the headers are short or the engine "back cycles" or "runs on" but running with open headers is bad for the engine as it reduces the back pressure which your engine is designed to have to run properly. It may also be illegal in many areas because of noise.My '90 GMC Sierra 1500 is overheating a little,( I've changed the thermostat), can it be the timing?

You will burn your exhaust valves and possibly seize the engine. You need the back-pressure provided by the exhaust system. Why drive? You're not going far enough to get up to operating temperature and will sludge up you oil and cause excess wear on all moving parts.Here's the trick. Take an old sock and stuff it with cloth. It must be tight enough to seal off outside air. You'll do fine. We transported a blacktop modified as soon as it was tied down and the headers were always plugged for the ride.

You may want to double check your jetting by reading the very base of the insulators after an open header run. Open headers cause lean mixtures with off the shelf carburetors. the insulator bases must look slightly tan and you'll know your mixture is about right.
If the plugs are white drop 2 jet sizes on the primaries and secondaries.
Is it safe to say we should just flush yesterday down the toilet?
Cork them!Open them at the track only.
Not only bad valves, think of your neighbors!
when you shut it off put a clean rag in the collector and this will stop cold air from reaching valves
