With the air meter secured to the supercharger inlet, it was obvious that a heat shield would need to be fabricated around the exhaust manifold. Ken removed the air meter to enable him to design a template that would be attached to the spark-plug shield brackets on the bottom and to the front valve cover screw on the top. The template design was transferred to a piece of thin sheetmetal to see how it would fit. After a number of trial bends, this revised pattern was traced onto 18-gauge sheet steel and folded into shape. He used spot-welds to hold the various bends and angles in place.
