yea if the head gasket is bad it will just run out the overflow and not run through the motor

So in other words the head gasket is blown letn compression from the cylinder leak into the water system causing it to pressurize the water system an push it out the over flow!

Using 93 octane might be the problem. My Athene kit did the ignition thing on 95 octane before I added octane booster,now it is fine.Ignition is caused by excessive combustion chamber temperature and the fuel ignites without any spark,therefore the timing will be out and therefore overheating.If you dont do something about it,you will crack a piston.
