I just bought a 84 w/302 4barrel >I want to cap off the heater.No problem ,I bought caps for that. My real question is does the bottom hose coming out of the water pump need to be hosed to the intake manifold or can I cap both the manifold port and the bottom water pump port. Some body said it will not hurt to cap both of these off,is this true or do I need to run a hose from the bottom port up to the manifold port. Thanks
