    Which heater hose do I tee into

    Which one of these heater hoses should I T or Y into in order to support the rear head cooling mod without adverse effects?

    Don't do it. They are prone to leak and drop into your cool cover right where the wires go through and cause a misfire. I have seen it numerous times at our ford store. Not only on marauders but other ones

    What exactly leaks? If it leaks from the T I create, i need to do a better job at tightening clamps or double clamp it.

    True. But we seen it happen several times
    Lots of heat back there and if you over tighten you stand a chance of leaking. As embarrassing as it is my marauder has leaked causing a misfire and is actually starting to leak again I just noticed. I just ordered new hoses.

    Yes. I'm going to connect both sides together then go to either a heater hose or back to the upper radiator hose

    Definitely install the cooling mod , and save yourself a couple of burnt , and bent valves from overheating #7&8 are notorious for this problem on the dohc motors.

    Yeah I'm going to. I just can't believe the factory messed up that bad on these cars. Sad.

    Prone to leak? Or YOURS leaked? It's a hose and a clamp. It doesn't get much simpler unless you used cheap ass clamps.
