    Upper water pipe? The steam vent that goes from head to head? If so, two little hex bolts on each head hold the fittings down.

    Or are you talking about the upper pipe on the water pump?

    you can use an fbody waterpump with spacers between it and the block to get the alignment back to the pullies.
