the water flows from the pump to the rear of the block ,then enters the head to flow back to the front of the head,and into the intake, across the intake and into the water pump.what Ive seen is that most Fe heads have casting flaws in the heads that restrict this flow,if you clean that up it can make a big difference in the water temp,another spot is at the rear of the block deck,open the water port entering the head,i know i know,everyone says it will crack the block and they are prone to crack there,Ive only seen one block in 33 years that had a crack there,the key is don't get crazy,just clean up the opening for better flow,that along with the higher volume pump and a good clean rad you should be able to stay cool.
