AFR 185 Cylinder Heads
Our NEW 185cc Renegade Ford is a clean sheet ground up redesign of our already formidable and proven 20° Ford Heads. These new 185cc flow drastically more, averaging a 17 CFM increase from .200-.600 lift, than our previous best 185cc. If you're looking fora decisive advantage for your small block Ford street/strip car, check out AFR's all new 185cc intake port emissions legal (CARB EO #250-3) performance cylinder heads. With lightweight 8mm 2.020 intake valves, 1.600 exhaust valves, combustion chamber volumes of 58cc or 72cc, and 70cc exhaust ports, AFR's new 185cc Ford cylinder heads are designed for 302-367 cid engines operating from 1500 rpm to 6500 rpm. A 3/4" thick head deck makes the AFR head ideal for nitrous or blower applications. Will not accept rail rocker arms. Hardened pushrods required with cylinder heads #1420 and #1422. High flow 2.020 valves might require aftermarket pistons notched for valve clearance. Note: 1986 5.0L must have pistons notched for clearance
