Every head that leaves indy/aeroheads shop needs a bowl blend because there's a very shallow and unsteep throat cut. The heads I had brought me by customer went on my bench and flowed a whopping 213 cfm @.450 and then went 201-203 after that.
Didn't they list the heads as basically a "Rebuilt" head with a 2.02 available upgrade?
For myself, a stock head flows in that area as I have constantly read. Which isn't bad for "In General" performance on the street.
Have you closed those (actual or like) heads after you have bowl ported them? Im wondering what you have found cfm wise.
