I have a 86 model camaro and i built a new motor for it. The problem that im having is that the left head is about 30 to 40 degrees warmer than the right head. I put some eldebrock performer heads on it with a cam that is just a little over .500 lift. I also have a new aluminum waterpump and a 160 stat. The carb is a new holley 650. I also checked the temps of the header tubes and there is also the same temp difference. I have checked for vacuum leaks, even went as far as pulling the intake and the head to see if there was something bolcking the water passage. THe same thing is happening with the stat removed to see if i have an air pocket. I have never had this happen before and I have built many motors. Any info would be appericated.
