LIFTER
VALLEY PRESSURE VENTS
These vents are a key part of any highly efficient oiling system. They allow crankcase pressure to rise unobstructed, allow more speedy oil drain back to the oil pan and stop a large portion of the unwanted oil drain back over the cam area that causes excessive windage and power loss. Existing holes in the block are simply tapped and vents screw in.

OIL
FLOW RESTRICTOR PLUGS
These plugs solve the common high-performance engine problem of too much oil in the head area. The plug restricts approximately 75% of the oil to the top end of the engine for better lubrication and prevents oil wastage at the lifters (which will cause windage problems). This also keeps the sump better supplied with oil. Installs easily into the back of the block in place of the stock plugs. Not for use with hydraulic lifters.
