       Finite element method used to calculate Pyramid head volume and surface area (back) A Pyramid Head is a 4-valve head where the valves may be canted as well as angled. This permits the creation of high compression heads above a flat-top piston for high bore-stroke ratio cylinders. This picture shows the computation output of a head profile to scale where a finite-element mesh is used to compute clearance volume and the surface area of the head
