Dart 9 Deg Chevy Head
Billet valve cover for Dart 9 deg Chevy Head
These precision machined billet valve covers are machined from billet 6061-T6 aircraft alloy. They begin life as one large hunk of aluminum and are machined down to their final shape. Most other solid billet valve covers tend to be quite heavy. The reason being is a thicker wall allows for faster material removal because of less tool chatter the down side of this is a heavy part. We go the extra mile taking light finishing cuts which result in impeccable surface finish and a lightweight part. Our valve covers also utilize a special steel bushing that protects the surface around the valve cover bolt holes from wear and over tightening. These bushings also eliminate the need for washers, which can potentially fall into the engine.
