if one already has the bypass kit that installs on the cylinder head, would it help to also run the freeze plug plate that is threaded on the back of the block, run a line from that plate and tie it in to the cylinder head bypass?
What if on a stricked puller you ran the heater hose from the head port down to the return/ other port below the water pump. This would take the heater core out of the system, would it take any pressure off of the system? I also have two 1/4 inch holes in the thermostat.
