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.\u003c\/p\u003e\u003cp\u003eNote the \u003cstrong\u003e+.500\u003c\/strong\u003e designation and the 5.46in 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 \u003cstrong\u003eexhaust\u003c\/strong\u003e valve - the matching part on the other side of the chamber is FERF2257P, the 2.125in Competition Plus intake valve.
