Description
This Titanium exhaust valve listing is organized specifically for Titanium Series Chevrolet Big Block, with the available dimensions presented as selectable configurations for easier cylinder-head planning. The parent listing is distinguished by Part #11921B-8, which should be cross-checked against the rest of the engine combination.
If the Titanium Series Chevrolet Big Block cylinder head has been ported, fitted with oversized seats, or changed from its original valvetrain layout, confirm the required valve measurements after machining rather than using a stock-size assumption.
