Ash,

It is not that simple, water is sucked in to the engine from the bottom of the radiator on the right hand side of the engine quite low down, the only place the water can get out of the engine is through the aforementioned port in the head along side the rear most inlet port.

Also the thermostat housing was bolted to the inlet manifold unlike the pinto where it is cast into the front of the head I believe.

So two problems really, the first is an inlet manifold to take some bike carbs that has a take of for the water (that bit I can cope with), secondly fitting a thermostat into the system, not essential, I have run cars without them, but I would like one.

I bet if I look, CBS do some sort of inline thermostat housing, that is the trouble with typing a long post I think of the answer by the time I have got to the end. Saves me lying awake all night pondering it though.
