Manton's Billet Aluminum Valve Covers are CNC machined from solid bar stock. They have been designed to come standard with fully baffled breather on one cover and the other will include a fill port with a Billet CNC Machined aluminum fill cap. We have CNC machined the coil mounts directly into the billet covers (not welded), to ensure proper coil placement every time.
