2 steps forward, one step back! heater motor has to go. had to pull the pass. side valve cover, and the master cyl. to get the motor in. raised port heads flow great, but they are sure a pain in an A body. have to get an offset master cyl. adapter, and go to an aftermarket hotrod heater thats all inside. looks like there might even be trouble w/ the offsett and mopar performance valve covers!!:banghead:
