AFR 205cc SBF Outlaw Race Cylinder Head
The Most Powerful Standard Street/Strip Head Ever
If
you’re looking for the world’s finest street/strip head
available, AFR’s 205cc aluminum cyilnder head is your answer. With lightweight 8mm 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 73cc ultra high flowing exhaust ports.
Note: 2.080 valves will require aftermarket pistons notched for valve clearance. (see footnotes here)
