Hi All,

Its been a while, and probably a moot point now because so much time has passed. However, I finally got to take my AIRWOLF 220 heads to a reputable head/ engine shop in the last couple of weeks (yes 4 years later...I know)

The shop were initially skeptical of the advertised numbers but were impressed with the results and the quality of the heads generally...here are the results;


Lift .100 .200 .300 .400 .500 .600 .700 .800 .900
Cyl 1 Int Corr. CFM 61.7 137.9 203.2 256.0 290.8 297.8 304.4 309.1 312.6
Cyl 1 Exh Corr. CFM 58.4 110.0 147.3 175.5 194.4 209.6 218.8 221.8 222.4

I'll try and show you the full sheet once I work out how to load it (PDF).
