AFR heads entire SBF line is CNC ported from AFR to produce the highest flowing, highest velocity cylinder heads on the market today. AFR pioneered CNC cylinder head porting and was the first company to offer a full line of economically priced cnc ported cylinder heads to the aftermarket.
Today AFR has established the standard for comparision in the SBF head world. The 165 and 185's are benchmarked on 302 and 347 stroker combinations as well as 351 and larger engines looking for a low rpm, torque combination. Argueably the most versatile head today the AFR 205 fits high RPM NA and poer adder 331 and 347's all the way up to 408 and 427 street oriented applications. When a larger head is considered the AFR 220 is the gold standard for inline valve high flowing economical cylinder heads. Easily capable of 600hp in a basic naturally aspirated combination or in excess of 1200hp with a power adder they offer a great value for the small block Ford. Bang for the buck it's hard to find a better flowing, higher performing cylinder head than the 220.
