Description
Built around the requirements of Big Block General Motors, this Titanium 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 Part #11490B-8, which should be cross-checked against the rest of the engine combination.
If the Big Block General Motors 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.
