    The Maximum Bolt-On Emission Legal Street/Strip Weapon!

    AFR's NEW 195cc Renegade Ford cylinder head almost defies the law of physics by flowing a whopping 315 CFM from a modest sized intake port. This head comfortably outflows its 10cc larger predecessor and is on the heels of AFRs previous best SBF inline head. If you want the maximum emission legal street/strip horsepower small block Ford 20° cylinder head, check out AFR's all new 195cc intake port emissions legal (CARB EO #250-3) performance cylinder heads. With lightweight 8mm diameter stem 2.050'' intake valves, 1.600'' exhaust valves, 58cc or 72cc combustion chambers, and 70cc exhaust ports which are raised .125'' higher than stock. AFR's new 195cc Ford cylinder heads are designed for 367-392 cid engines operating from 2000 rpm to 7000 rpm. A 3/4'' thick head deck makes the AFR head ideal for nitrous or blower applications. Exhaust port and bolt pattern are raised .125'' (1/8'') higher than stock, this rarely affects header or chassis fitment. Will not accept rail rocker arms. Hardened pushrods required. High flow 2.050 valves might require aftermarket pistons notched for valve clearance. Made in USA.
    Installation Note: 1986 5.0L must have pistons notched for clearance.
