I have two ports in my manifold & two in the water pump. One manifold port is being used for the guage cluster and I plan on using my heater core. The question would be, can I put a tee fitting in the last manifold fitting to attach the heater core hose and fan temp sensor. I have aluminum heads with no ports. I think my best bet is to purchase a thermostat housing with a sensor port. What are your thoughts? Thanks
