From the all out competitor to the performance street enthusiast the Champion GN1 aluminum head is the preferred choice. In 1990 we had a goal. Produce an aluminum cylinder head for the Buick V-6 turbo that was superior in both performance and affordability than anything on the market. In 2002 more than a decade after establishing this goal the Champion GN1 head has achieved this many times over. With hundreds of heads in service the GN1 head is a proven winner.

Key design features for the GN1 heads: * Valves are moved closer to cylinder bore centerline to unshroud valves for more flow. * Spark plugs are moved closer to cylinder bore center for improved combustion * Special combustion chamber shape for maximum efficiency. * Large 1.900" intake and 1.600" exhaust valves. * High flow as cast intake and exhaust ports. * Accepts stock rocker arms and stock valve covers. * Lightweight compared to cast iron head. Champion GN1 aluminum heads will accommodate stage I or stage II blocks and three different rocker arm configurations. They are available as complete assembled units or fully machined bare castings. On the track or the street the Champion GN1 Aluminum head for the turbo V-6 is an excellent choice.
