BILLET ALUMINUM VALVE COVERS:
These truly are a billet cover not just the rails. These valve covers start off as one big block of aluminum and are completely CNC machined. They have provisions for screw in breather(s) and screw on oil filler caps. They are also provided with internal baffles to prevent oil spray at the breather. They are anodized and can be custom engraved as an option. These valve covers were meant to clear after market rocker arms and are extremely rigid to minimize any type of oil leak.
Pictured below is a Small Block Chev valve cover with a typical logo with the same features as the Chrysler valve cover. Pictured to the right is the breathers that we use. It's a K&N element and our CNC made holder. Notice that these are a screw in holder and is sealed with an O Ring. Valve Covers can be ordered with any combination of breather and oil filler cap and comes with allen bolts, gaskets and internal baffle. When ordered complete these are truly a drop on unit.
