Personally, I'd just do like a marine engine, and water jacket part of the exhaust system (manifold on non-turbo engines). Then, up-size the radiator and such accordingly, so you can leave the exchanger in the loop full-time (it should be the last thing to see coolant before discharge to the radiator when the t-stat is open).
