Less Weight, More Power

18° X-Series Aluminum Cylinder Heads
The X head is the best of both worlds: 18° horsepower, no expensive shaft mount rockers or offset lifters required. It offers a dramatic horsepower gain over 23° cylinder heads, ideal for budget-minded racers who want to go faster. Other advantages are raised 245cc intake ports that flow over 320 cfm out of the box, 68cc combustion chambers, and 2.140" intake/1.600" exhaust valves.

Track-1 Aluminum Cylinder Heads
For drag or oval track racers who want lightweight heads that make a significant horsepower difference, Track-1 heads have thick decks, 221cc intake ports, 67cc combustion chambers, 1.600" exhaust valves, and 10° steel retainers. They are nitrous-compatible with installed phosphorous bronze valve guides and hardened valve seats for unleaded fuel. Spring pockets must not be cut more than 1.550".
