It is built to meet or exceed the specification of the original equipment part it replaces, giving a reliable, leak-free seal between the intake manifold and cylinder heads. The set is finished in white and supplied as a single complete kit, so every gasket needed for the job is included in one package rather than sourced piecemeal.\u003c\/p\u003e\u003cp\u003eThis gasket set is designed for MCM\/MIE GM V-8 (305 and 350 cid) marine engines, including 1986 and older applications, and covers the 898 (198 HP), 200, 228, 230\/260 (Inboard), 230, 250, 255, 260, 280, and 5.7L Ski engine configurations.
