AFR 185cc Non-Emission Legal
SBF Outlaw Street/Strip Cylinder Head
|
No Heat Riser Or Air Pump Holes
The Maximum Street/Strip Performance
|
|  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) aluminum cylinder heads. With lightweight 8mm 2.020 intake valves,
1.600” exhaust valves, combustion chamber volumes of 58cc
or 72cc, and 68cc 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. Available with optional nitrous or blower exhaust port featuring 70cc ultra high flowing exhaust ports. 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.
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 #8047, 1.290 O.D. with higher spring pressures
to reduce chances of valve float associated with rpm’s 6200
or higher. (see footnotes here) |
