Extra Tall 3.75″ 12 Valve Billet Valve Cover fits Cummins 5.9L Notched for Stock Lines

3.75″ extra tall one piece billet valve cover fits 5.9L Cummins 12 valve. Will not fit under stock cowls. 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. 1/2″ taller than our regular billet covers which are already taller than stock covers. Clears most all aftermarket studs. 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. Comes with one -12AN port in the top of the valve cover unless otherwise requested.
