All ADA Racing billet heads are made from 6061-T6 aluminum and CNC machined for consistency and performance. Clear anodized for protection against corrosion. This is the head shell only. Includes orings that fit into the grooves in the head shell and brass fittings. Girdle kit & domes not included.
Exhaust mount bracket is sold separately and is required for any exhaust that mount to the head, like the stock exhaust. The stock exhaust will have clearance issues with the girdled head shell and will require modifying the stock bracket/exhaust to clear the front exhaust side corner of the girdle head shell.
