Just put in new Edelbrock valve covers and have had nothing but problems because they’re bulkier than the old ones. Interference on passenger side with bottom heater hose and with alternator. Very difficult to get the bolts installed, but got that all hashed out. The drivers side was easier to install, but the throttle arm is now hitting the corner of the valve cover and preventing the arm from going to idle, very high RPMs. I don’t see a way to adjust it. I see that there are adjustable rods available. Would this solve my problem? If so, suggestions on which one to buy? Won’t this limit my pedal travel? I like the look of the valve covers but I regret getting them at this point, they really don’t fit.
