Hi Guys, long time no speaky! need a bit of advice re manifolds, I have a Perf RPM on the mock up engine in the Cobra, there are four threaded holes on the top two front two back, what purpose do others use them for? also due to fittig a spitfire heater, I plan to input to the heater matrix from the water pump, where would be best to flow the output to? I have a header tank fixed to the rear bulkhead with a pipe to the bottom rad hose and the overflow to the T-Stat housing, I will probably be fitting a Victor on the stroker, I dont know what the takeoffs are on that manifold? thanks for any advice/pics.
