Description
All ADA Racing billet heads are made from 6061-T6 aluminum and CNC machined for consistency and performance, anodized clear for looks and protection against corrosion.
This listing includes the head shell, O-rings that fit into the grooves in the head shell and brass fittings. This head uses the stock O-rings in the top of the cylinder.
Please note that the water routing is not the same as stock. Water is routed in to the head pipe of the exhaust and exits out the head to the water bypass. Or vise-versa depending on water temperature.
Also note that base gasket thickness will also affect your compression. The thicker the base gasket, the lower your compression.
