Set of 2 new intake manifold gaskets to fit Buick vehicles from 1957-1966 with 364, 400, 401, 425 CID nailhead engines.
Intake manifold NOT included.
We also sell the hardware to plug your intake manifolds exhaust crossover ports, which will prevent the fuel from boiling in the carburetor and causing a hard start condition which is common in Buick nailhead engines running ethanol fuel.
Our exhaust port block-off kit will also give an additional 18 horsepower boost by keeping the intake manifold cool.
