Roy,
Yes I have Tom Langdon's spacer behind the thermostat housing. I am not running a heater. So I routed copper over the top of the water pump to a 90 degree elbow. Then another pipe under the headers and intake an looped it back on to the intake. From the the other side of the intake I went directly to the spacer. I had another thread here where I asked if I could bypass the long loop under and over to get to the water pump, but that is what is going to move the water so I don't believe you can eliminate that part.
