    AFR's Ultimate SBC Head
    with Standard Valve and Stud Locations!

    AFR is reviving their popular 220cc powerhouse 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 the 180cc, 195cc, and 210cc series cylinder heads. These cylinder heads do not require offset rockers of any kind, yet they are still able to easily flow numbers that are in raised runner head territory. The Competition Package Race Ready CNC Porting Eliminator Head flows 329 CFM which is enough airflow to reach that elusive 700 HP mark in aggressive drag race trim while allowing you to retain all of your standard valvetrain components. Displacement ranging from a high RPM 350-427ci with naturally aspirated 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. Getting this much flow from a stock geometry 23° head is an extremely impressive accomplishment. As always they come with AFR's trademark 3/4'' thick head deck (ideal for nitrous or blower applications). Standard valves are lightweight 8mm diameter stem, 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'' (1/4'') over GM L98, this rarely affects header or chassis fitment. These 220cc aluminum cyilnder heads are available in either standard port or spread port exhaust configurations. Spread port heads have the center exhaust ports spread apart 5/8'' over stock L98 GM heads. The reason for spread port heads is to achieve additional cooling in the center of the head where the heat concentration is greatest. As standard headers do not fit, spread port headers are required since the center ports are spread further apart then stock GM products. The increased spacing on the exhaust port also requires the use of exhaust gasket Fel-Pro p/n 375-1409. Spread port heads only come with a Stahl bolt pattern. AFR's spread port head has all the benefits and features of AFR's standard head. .
