Product Description

AFR 220 Competition Ported Cylinder Heads - #1112

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 2.100 intake and 1.600 exhaust with AFR's hardened ductile iron interlocking seats. Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised .250 over GM L98, this rarely affects header or chassis fitment.

    These are replacing my old Canfield heads and they look totally insane. Much better quality than my antique heads. Thanks for everything.
