Description

The Mr. Gasket 6091 is a kit of 12-point intake manifold bolts designed for a variety of American Motors, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Oldsmobile, and Pontiac V8 and V6 engines. These bolts are constructed from Grade 8 steel with a zinc-plated finish for durability and corrosion resistance.

Each bolt features a 12-point head and a flange, with an underhead length of 1 inch. The kit includes special extra-thick flat washers to ensure optimal clamping pressure. These bolts are ideal for applications where space is minimal, such as with larger runner race manifolds.
