Ferrea Competition Plus Intake Valve Set Chevrolet Small Block 2.125in Head 11/32in Stem - Set of 8

A set of eight intake valves from Ferrea's Competition Plus line for the Chevrolet small block, with a 2.125in head diameter, an 11/32in stem and an overall length of 5.45in. These are 12-degree valves carrying Ferrea's S-Flo head form, cut for 12-degree cylinder heads rather than a stock 23-degree head - fitting them to the wrong head angle will not give you the seat geometry or the valve-to-piston clearance you are expecting.

Note the +.500 designation and the 5.45in overall length: this valve is longer than a standard small block valve, which changes your installed height. Plan on checking spring installed height, retainer-to-seal clearance, valve-to-piston clearance and pushrod length against the assembled engine rather than assuming a stock valvetrain will carry over. This is the intake valve - the matching part on the other side of the chamber is FERF1478P, the 1.625in Super Alloy exhaust valve. Intake and exhaust valves are not interchangeable.
