I plugged off mine as well when I did my install based on the recommendation of my engine guy..like hugger says I caught a lot of flack for it..so much that I removed the plugs a plumbed the steam into the top of the water pump next to the hose outlet...it was explained to me that plugged off you will get hot spots in the heads.it was no trouble..I just drilled and tapped a hole in the water pump..and hooked it up..
