These aluminum cylinder
heads come ready for the maximum street/strip Small Block Ford performance
possible. They are not emissions legal. The 165 comes with lightweight 8mm
1.900 intake and 1.600 exhaust valves and the 185 sports 8mm 2.020
intake and 1.600 exhaust valves. Both cylinder heads feature 58cc or 68cc
combustion chamber with 68cc exhaust ports. Both the 165cc and 185cc
have available as an option nitrous or blower exhaust ports featuring
a 70cc ultra high flowing exhaust port. With AFR’s
trademark 3/4” thick head deck, it’s no problem handling
that additional cylinder pressure. Each head is also drilled for
the larger 1/2” head bolt hole for maximum head gasket retention
as a standard feature of this serious race piece in street disguise.
