BBC 24° Stainless Steel 2.250 x 5.500 O.a.l 11/32 Stem Race Intake Valve, Ea.

Race-spec intake valve built to match AFR 24° head geometry without compromise.

• ▸2.250-inch head diameter delivers genuine flow gains over stock
• ▸Stainless construction survives sustained heat cycles and high-lift cams
• ▸5.500-inch OAL and 11/32 stem sized for AFR's porting geometry
• ▸Resists fatigue where cheaper alloys start to give up

“Where the build starts. Everything downstream answers to it.”

Budget valves fight the head geometry they're fitted into — this one is dimensioned specifically for AFR's 24° Big Block Chevy castings, so the porting work you've paid for actually reaches the combustion chamber. Stainless construction holds up under the heat cycles and high-lift profiles that accelerate wear in lesser materials. At this price point, it's the sensible choice for any serious BBC build.
