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.
I wouldn't bother spending any money trying to port a set of 270 heads. If you want to spend money to make more power spend it on the intake. There are no really nice OOTB 700 to 800 hp intake manifolds for MW ports. The Super Victor is pretty good but not great, the Indy stuff is okay but needs work to be great. I've heard the new TF intake is good but I haven't seen one yet. They made a few and then ran out.
