How about just redirecting the return hose to pass near to the exhaust manifold. Machine a flat on the exhaust manifold and have a ally heat exchanger that can be move to contact with the flat surface on the manifold. The flex of the rubber hoses should be enough to allow a two inch gap to be made between the exchanger & the manifold when the temperature is reached. For extra control insulation could be slid in as the heat-xchr moved out.

(just realised - would need to move the thermostat valve outside the block - with a separate circulating hose bypassing the rad)
