These AFR 185cc SBF Street/Strip Outlaw aluminum cylinder heads come ready for maximum small block Ford performance. They are not emissions-legal. The 185cc heads come with lightweight 8mm, 2.020 in. intake and 1.600 in. exhaust valves. These cylinder heads feature 68cc combustion chambers with 68cc exhaust ports. These heads have an available nitrous or blower exhaust port option featuring a 70cc ultra high-flowing exhaust port. With AFR's trademark 3/4 in. thick head deck, it's no problem handling that additional cylinder pressure. Each of these serious race pieces in street disguises is also drilled for the larger 1/2 in. head bolt hole as a standard feature for maximum head gasket retention.
