Description
This Manley Titanium exhaust valve family is intended for Big Block General Motors builds where valve dimensions need to be matched deliberately to the cylinder head, seat work, and valvetrain geometry. The parent listing is distinguished by Part #11483-8, which should be cross-checked against the rest of the engine combination.
For Big Block General Motors, valve diameter changes can alter seat work and chamber/shrouding relationships, while alternate overall lengths can change installed height and rocker geometry.
