AFR 220 SB Chevy "Comp" Ported Cylinder Heads - (75cc)
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.
