The Indy heads seem to wake up some with porting, and I've seen a few people change the 295/325 intake valve to 2.25 to pick up some additional flow. Would the Trick Flow 270's benefit any from porting or are they pretty much tapped out since they started as the 240 casting?

For a wedge with stock exhaust port location it doesn't sound like there are any better options than the max wedge sized EZ's, or the TF270.
