Description:
|
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) cylinder heads.
With 2.020 intake valves, 1.600” exhaust valves, combustion chamber volumes of 58cc or 61cc, and 69cc exhaust ports, AFR’s new 185cc Ford head is 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. Will not accept rail rocker arms.
Hardened pushrods required with 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.
Note:
Hydraulic roller cams typically experience valve float at 5800-6000 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8032, 1.530 O.D. with higher spring pressures to reduce chances of valve float associated with rpm’s 6000 or higher.
