4BT Billet Valve Cover fits Cummins Notched for Stock Lines

In production for over 20 years, Keating Machine is the original company to produce a true one piece billet valve cover. Keating Machine set the standard for one piece billet valve covers long before they were common in the diesel performance industry. One piece billet valve cover fits 4BT Cummins 8 valve. Notched to fit over stock injection lines. We also have non-notched valve covers for engines with aftermarket injection lines that go over the top or around the valve 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. Contact us before ordering if you want a -12AN breather port added to the top of the valve cover.
