Description
Built around the requirements of 2.020 Triple Groove Hollow Stem, this Race Flo intake valve family gives engine builders a focused way to select the dimensions their cylinder-head combination calls for.

If the 2.020 Triple Groove Hollow Stem 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.
