HouckCO Someone ask what the advantage of Fenton split manifold was...this may be one of those advantages !! The intake always cooled by incoming fuel/air mixture doesn't suffer as bad as the hot exhaust,especially on trucks that are loaded and really working hard. In the olden days you had a head suracer that was just a stone on an iron surface plate. Now it's liable to be a Blanchard super surfacer expensive to use,lot of trouble to set up on something hard to get a grip on.
