AFR 205cc SBF Outlaw Race Head

The Most Powerful Standard Street/Strip Head Ever

If you’re looking for the world’s finest street/strip head available, AFR’s 205 head is your answer. With 2.080 intake valves, 1.600 exhaust valves this head moves tremendous volumes of air through conservative runner volumes, spelling big torque and horsepower numbers. With combustion chamber volumes of 58cc or 72cc accompanied by 70cc exhaust parts which are raised .125 higher than stock, AFR’s new 205cc is the ultimate choice for 331 through 392 engines operating from 3500 RPM to 8000 RPM. AFR’s trademark 3/4” thick head deck makes them ideal for heavy nitrous or blower applications. With available optional nitrous or blower exhaust ports featuring 75cc, 80cc ultra high flow exhaust ports.

Note: 2.080 valves will require aftermarket pistons notched for valve clearance.
