Description
Dart's Pro1 Mercury Racing cylinder heads are perfect if you need a little more power, and are true bolt-on replacements patterned on professional competition heads. The intake ports are precision-cast from C355-T61 aerospace aluminum, come available with 310cc, 325cc, or 345cc intake runners, and have the correct exhaust bolt pattern for factory manifolds. The yellow chromate surface treatment inhibits salt and corrosion for marine usage. They are available bare or assembled. Choose the right configuration for your motor and any special parts and considerations. Assembled heads also include Inconel exhaust valves to withstand extended running time and temperatures.
