ADA Racing Cylinder Head

ADA Racing billet heads are made from 6061-T6 aluminum and CNC machined for consistency and performance. Billet head shells are clear anodized for protection against corrosion and includes o-rings that fit into the grooves in the head shell and brass fittings for waterlines.

ADA Racing billet domes include compression and dome top o-rings. Squish relief is set specific to each individual model.

ADA Racing Girdle Kits include all hardware and brackets. No cylinder mods required for girdle kit, just bolt it on! The ADA Throttle/Choke Cable Bracket is required when using stock carburetors with ADA Billet Girdle Head. This bracket has the throttle cable mount moved up, so it does not interfere with the girdle bracket.
