That's interesting. When I check the crossover with my infra red temp gun,(when idling,) the drivers side is usually 10 degrees cooler. I'll check it after a spirited run and see if that changes. The heater connection is one I got from Performance Years and was the one with the restriction. It's different from the one I took out which had the spring.
