Without seeing it,that is how I imagined it would operate.So the last cylinder head must be the hottest part of the engine.Really speaking the rear pipes need to go.The water pump should have been redesigned to feed both sides of the vee equally,the coolant should have come up through the block deck and into the heads and then out to the top of the rad.The addition of cooling jets run off the main oil gallery which I presume is under the camshaft,central in the block would have eliminated the skirt scuffing.My other gripe is I dislike dry liners.Quite amazing how so many gave reasonable service.
