*--new 220cc flow a massive 340 CFM, averaging an 11 CFM increase from .200-.800 lift over our previous best SBF in spite of its 5cc smaller intake runner--
*--lightweight 8mm 2.100 intake valves and 1.570 exhaust valves, combustion chamber volumes of 58cc or 72cc, exh ports and bolt pattern are raised .375 (3/8”) higher than stock, but this rarely affects header or chassis fitment--
*--Exhaust port is drilled for standard 2” spacing that fit factory headers and also drilled for 3” spacing to accept larger O.D. headers--
*--AFR’s new 220cc is the perfect choice for 347 through 427 CI Windsor engines operating between 4500 to 8500 rpm--
*--With the largest intake and exhaust runner volumes for our in-line Ford line up, these are the ultimate for NMRA Renegade or Hot Street classes--also has standard 2” spacing and 3” spacing for larger O.D. headers that fit factory and aftermarket headers
*--see basic parts list for the included parts in the head assembly and some suggestions on manifolds and gaskets--
*--A 3/4” thick head deck makes the AFR head ideal for nitrous or blower applications--great tech help @ www.airflowresearch.com--
Note:High flow 2.100 valves might require aftermarket pistons notched for valve clearance--Will not accept rail type rocker arms--Hardened push rods required on all applications due to the hardened guide plate being used--
