Item Description
Outlaw heads for the street or strip from AFR!
These AFR 165cc SBF Street/Strip Outlaw aluminum cylinder heads come ready for maximum small block Ford performance. They are not emissions-legal. The 165cc heads come with lightweight 8mm, 1.900 in. intake and 1.600 in. exhaust valves. These cylinder heads feature 58cc 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.
