What’s the Difference Between a Ford 351 Windsor, Cleveland, or Modified Engine?

DIRECTIONS:

Surfaces should be clean and dry. Apply an even, continuous 1/8" bead of silicone to one surface, surrounding all bolt holes. Remove excess at once with knife. Assemble parts immediately. Do not squeeze out silicone by over tightening bolts. Silicone fully cures in 24 hours. Replace cap after use. Clean hands with dry cloth. Clean tools with non-flammable cleaning fluid.

Note: Not recommended for use on head gaskets or parts in contact with gasoline.
