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. Set of 8 valves Intake valve, not interchangeable with the exhaust side Ferrea Competition Plus product line Head diameter 2.125in Stem diameter 11/32in Overall length 5.45in 12-degree valve, S-Flo head form +.500 length designation, longer than a standard small block valve Application: Chevrolet small block
