Tall LS Race Bare Billet Valve Covers w/ Motion Quick Release Breathers 10-171

This valve cover was built out of desire from the market.  A bare bones billet valve cover with Burn Down breathers and no other ports or oil caps. While this valve cover utilizes burn down breathers with 12, 16, and 1.250" hose connection, we do now include baffles for the underside of this burndown to reduce oil into PCV system/burndown box.

Note: these were built with extra clearance, but are not guaranteed to work with every LS cylinder head and valvetrain on the market. Please do due diligence with measuring before purchasing, once a valve cover is installed we will not return.

These measure 1.56" (Figure 1) from the mounting surface to the inside of the top of the valve cover, and the gasket adds an additional .050 to .100 for an overall clearance over 1.60".  Additionally, the reinforcement points for the valve cover bolts measure 0.375" tall inside the valve cover. Please measure your clearance before ordering to insure fitment. See picture below (Figure 2) for reference.

Coil-Packs

Due to utilizing large burn down breathers, these covers do not come with any coil pack mounting provisions and will require remote mounting of the coils.

Oil Fill

In order to provide maximum valve train clearance versus valve cover size, these do not have any oil cap provisions and will require removing covers or filling through burndown ports, or dry sump oil tank fill.

Breathers

These are designed to work with a common 2 bolt style "burn down" breather fittings as supplied. Breathers can be changed to point either forward or backwards and use an Oring seal to seal against valve cover.
