Has anyone got any HP gain or loss figures for heated vs unheated manifolds?For div 2 or 3 type tractors since they require factory only.Given the current craze for lp I wonder how much benefit all else equal port size etc.Also any dyno nos. for Steels repro or Dennys tubular compared to stock?

Cold air is denser and the denser the better!
