Product Description

AFR 220 SB Chevy "Comp" Ported Cylinder Heads SP - (65cc)

Air Flow Research is reviving its popular 220cc moniker due to overwhelming request from customers for a larger bolt on standard valve location head. Unlike the previous 220, the new Eliminator version requires no special parts. Valves and studs are in stock GM L98 locations just like our very popular, 180, 195, and 210 series heads. They do not require offset rockers of any kind yet are still able to muster flow numbers that are in raised runner head territory.

This 329 CFM cylinder head that is perfect for someone wanting to retain all their standard components while still having the airflow to reach that elusive 700 HP mark in aggressive drag race trim. Displacement ranging from a high RPM 350 to a 427 CID with natural applications in the various sportsman classes, bracket/drag cars, oval track, and larger displacement street machines with typical operating ranges between 4000 to 8000 RPM depending on application.

As always they come with AFR’s trademark ¾” thick head deck, ideal for nitrous or blower applications. Standard valves are lightweight 8mm valve stems with 2.100" diameter intake and 1.600 exhaust valves with AFR's hardened ductile iron interlocking seats. These heads feature a 65cc combustion chamber for more compression. Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised 1/4 inch over GM L98 castings. This rarely affects header or chassis fitment.
