64 barracuda overheating issues

Thanks for the responses, wouldn't trade them in for gold...I can probably come close to the record as how fast does it take to change a thermostat..today I installed a 195 degree seems to be ok. Recirculated hot air around the engine today idling for 20 min..seems to be ok went just a touch over 1/4 mark..I also drilled 4 tiny holes in thermostat...excellerated it several times it maybe ok...possibly the other thermostats where staying open..I'll have to drive it see what happens..
