Billet Half Moon Set

This Billet Half Moon Set is designed to replace the original rubber half moons at the front and back of the head.  The old half moons always leak and we just can't have that! These are guaranteed not to leak and they look awesome!

Due to variations between the many different castings, these half moons may need to be slightly modified along the inner top edge (we have tried to make these as universal as possible).  Any required modification can usually be done easily with a small file.  After a test fit and any required modification, the half moons should be installed with a small bead of RTV Silicone along the bottom edge.  It is important to install the valve cover immediately after the half moons are installed to hold them in place until the silicone has dried.

These are custom made for
