These Dart cylinder heads have highly efficient chambers with race-proven features, including rolled valve angles, an improved spark plug location, extra-long intake valves, raised exhaust ports, and fast-burn chambers. Assembled heads include super-tough Inconel exhaust valves to withstand the extended running times and temperatures typical of marine usage.
