Thank you for the great read! After reading this article I am convinced the best heat method (for me) is the heat valve flapper method provided by original Chevy engineering. I'm lucky I found a '53-54 Corvette type dual exhaust with the integral heat chamber. I have used the Fenton headers for 15 years on a daily driver only vehicle year 'round. My only criticism of the two little copper pipes to the bottom of a home-made heat plenum is 'I don't like the way it looks'. By reading the above article I believe that heat will be present initially and then titrated as the engine is warmed, a more ideal situation and one that may yield me another mile per gallon. Actually this could be set up as a lab experiment ala Stovebolt Mythbusters!
