Thanks for your input Tim. The engine I am painting is a marine conversion with water cooled exhaust manifolds and does not have the usual heat riser valve on the left exh manifold. I am assuming that even with a more or less open exhaust some hot gas will be directed through the intake manifold?

My experience with marine engines is that they are usually in an tightly enclosed space and cooling is more of an issue than heating. My gut feeling is that after a few minutes of operation the intake will draw and retain enough heat from the heads to aid fuel vaporization.
