195cc SBF "Renegade" 20° Street Head

The Maximum Bolt-On Emission Legal Street/Strip Weapon

Our new "Renegade" Ford heads are a reengineered ground up redesign to our already formidable and proven 20° heads. These heads come ready for the maximum street/strip Small Block Ford performance possible. AFR’s 195cc feature lightweight 8mm 2.050 intake and 1.600 exhaust valves with options for either 58cc or 72cc combustion chambers. The 195cc's 70cc exhaust ports and bolt pattern are raised .125 over stock, this rarely affects header or chassis fitment. With AFR’s 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 for maximum head gasket retention as a standard feature of this serious race piece in street disguise.

Note:

195cc Competition Package exhaust port is raised .125.   (see footnotes here) for additional information.
