12 Valve Billet Valve Cover fits Cummins Notched for Stock Lines Pocketed
One piece billet valve cover fits 1994 to 1998.5 Cummins 5.9L 12 valve engines. 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. 3.30″ 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. Sealed with individual o-rings to head. If you have a First gen 1989 to 1993 engine we have valve covers for those engines also. Optional port in top of cover includes disc milling internally to connect two of the individual pockets together so they are connected by the additional port. All of the pockets can not be connected together because of the notches to clear the stock injection lines. Single optional port is machined between cylinders 4 and 5.
