AFR focuses on mid lift flow numbers for their street/strip heads, which is what they call the 205. These heads are already flowing >.200cfm at .300" lift, and >300cfm at .550". Thats some pretty stout air flow for a 205 cc runner which equates to excellent port velocity. Check the other alum. heads on the market and none come close with even bigger ports. Check out
