14 Afr 185 Heads Flow Numbers , Everyone Loves It!. Afr 185 enforcer heads flow numbers. The plan would be to replace the heads with afr 185 renegades with 58cc chambers uping the compression from 9.7 to 10.2:1.head flow numbers for these heads are shown at the bottom.
Perhaps i am repeating the numbers but i have the westech article front of me here and the flow numbers for afr 185s. The afr 185's and 165's exhaust flow is nearly identical. I was planning to install the promaxx 9175 180cc heads on a dss 331 and its just a street car, so am wondering if these.
