I think the hose going to/from the heater core would work-it's in the same coolant loop as the engine (as opposed to the radiator). I bet you wouldn't have to move the block more than a few mm to stop the heat transfer.

I like this idea. maybe use a couple small springs to hold the block away from the manifold, and a pull-cable wrapped around the whole assembly to cinch it together when you want heat transfer. Maybe something like one of those spring-steel universal oil filter wrenches.
