Description

The Ultimate Bolt-On Emission Legal Street/Strip Weapon! - Information below is referring to fully assembled heads.
If you need the world´s finest street/strip small block Ford head, check out AFR´s all new 185cc intake port emissions legal (CARB EO #250-3) performance aluminum 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 302-351 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. Also available with optional nitrous or blower exhaust ports featuring 70cc ultra high flowing exhaust ports. These heads will not accept shaft mount 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:
Hydraulic roller cams typically experience valve float at 6000-6200 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8019, 1.270 O.D. with higher spring pressures to reduce chances of valve float associated with rpm’s 6200 or higher, but smaller cams with less than .500 lift can rev to 6500 rpm with the included springs.
Note: Stock 86-93 5.0L must have pistons notched for clearance.
