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.
Please note that base gasket thickness will also affect your compression. The thicker the base gasket, the lower your compression. All compression readings are approximate for sea level elevation on a stock non-ported cylinder.
Domes come as a set of 2 when selected in the drop down above.
Does not work on Direct Injection models, works with carbureted models only.
