Hi all - I think ditching thermostats is the old wives tale. Go back to the grass roots of engine design where a need was assessed to incorporate thermostats. Sixty three years on the engine is not as efficient through the water flow areas. Fix that and you should have no problems. Ditching thermostats is using the same rationale as to converting to 12v electrics. If you replicate the wiring correctly and not use modern wiring, no problems. Millions of vehicles utilised thermostats and 6v. Modern day restorers should recognise these facts.
