Don't let oil go to your head! Milodon oil flow restrictor plugs solve the common high performance engine problem of too much oil in the head area. They restrict approximately 75 percent of the oil to the top end of the engine for better lubrication and prevent oil wastage at the lifters (which will cause windage problems). This also keeps the sump better supplied with oil. These plugs install easily into the back of the block in place of the stock plugs. They're not for use with hydraulic lifters.

Oil Restrictors, .0625 in. Orifice Diameter, Chevrolet, Big Block/Small Block, Pair

Also recommended to be used on World Man O'War Ford Engine Blocks
