Description
Built around the requirements of Chevrolet Small Block, this Severe Duty intake valve family gives engine builders a focused way to select the dimensions their cylinder-head combination calls for. The parent listing is distinguished by 2.125"; Head / Part #11754-8, which should be cross-checked against the rest of the engine combination.
If the Chevrolet Small 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.
