12 Valve Billet Valve Cover fits Cummins Black Anodized

One piece billet valve cover fits 5.9L Cummins 12 valve. Designed for aftermarket injection lines run either over top or around front and back of cover. 3.25″ total height will clear most all aftermarket studs. Taller than stock covers. Also acts as a girdle for the rocker pedestals to help stabilize them when using high spring pressures and rpm. Engraved with Keating Machine logo on top. Contact us before ordering if you want a valve cover without engraving or custom engraved. Sealed with individual o-rings to head. We also stock these notched to fit over stock injection lines. Optional ports in top of cover includes disc milling internally to connect all of the individual pockets together so they are all connected by the additional ports. Single optional port is machined between cylinders 4 and 5. Dual ports are machined between cylinders 4 and 5 as well as between 5 and 6. Contact us before ordering if you want the additional -12AN breather ports added.
