here's my dilema, installed Fenton headers on my 235, installed heat plate under the intake, truck seems to run better, but here's the issue, the left side exhaust is warm and fairly clean, the right side is cool and pretty smokey, seems like it's running rich. My feeling is that there is a problem, maybe bad spark plugs or something to do with the valves. Anyone have any suggestions, or have had this problem too? Thanks!!! Go Navy!!!!
