Info

Notes

Heavy-duty, 1.89"" Inconel exhaust valves provide added durability for marine applications. Hard anodized black to protect the aluminum in the harsh marine environment. Sold with valves only to allow for valve spring choices, Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4"" reach with flat gasket seat. Spark plug is closer to center of bore, will interfere with high-dome pistons for open chamber heads.
