I reworked a set of CNC’d 220 AFR heads for a buddy that really sucked. I picked up well over 20cfm and did in fact remove a lot of the vane. I was a little afraid to go crazy but guys on LS are taking it all out. I was warned it gets thin there so don’t go super crazy.
On that particular AFR application, was that new heads you worked on or was that used heads where we can know how much ET it picked up? Just curious on that one.
The Trick Flow head is the one I would love to see with that vain and without it. I wish we knew if Trick Flow did dyno and track testing with and without that vain or if they just used it because it works in other platforms. We would never get a straight answer on that.
