I've searched and can't find an answer so here: offy dual intake on a 235 with Fenton headers. Want to water heat the manifold. Langdons says to take heat from Thermostat housing by putting a take-off plate between housing and block or to tap the housing. Any reason I couldn't 'T' into the heater hose that comes off the Thermostat housing and then return the water to the heater hose that is connected to the water pump? Seems easier than tapping the T-stat housing, but if I need to tap the housing I will. Plus while I'm fussing with the hoses I can put some little valves in after the 'T's to shut off the heater lines for when it's hotter than hell in summer time. Thanks, Scott
