Trick flow heads can and do make good power, plus you can run the 2.02" intake valve without having to go through piston notching. On the other hand, trick flows had a good bit of problem a few years back with their valve guides- some would drop a valve right into the combustion chamber. I have heard a few explanations for this, but most had to do with the angle of the the valve that is necessary to run the 2.02 valve without problems. Now trick flow claims to have taken care of this problem, but I heard too many horror stories to put a set on my car, and my cousin just spoke with Mr. Bell (of Kenne Belle SC's) and they have done a few test on the new trickflows and he stated that they too show signs of valve guide wear after a couple thousnad miles.
The AFR heads are all the rage right now, and so far they are making AWESOME power! I myself have been looking into buying a set of heads for my stang for about 2 years now. I was set on a set of edelbrock's becuase of their great quality, impressive flow, and they are factory port matched to my intake, but after the AFR head came out, I changed my mind. I ordered a set of 165/58cc ones last week and should have them shortly. I went with the 58cc for a little more compression, and I was going to have them milled until I looked into the probles associated with it. If you mill the heads, you must also mill the intake surface that meets with the head otherwise the angles will be off and you will have a leak, also, when you will the heads you may very well end up having problems getting your accessories to line back up with the holes that are driled into the heads since the heads will sit lower now.
If you are in fact going to add a 347 stroker to your car, the AFR 185 may be better for you. On a 302 they are a bit big on the intake side in terms of the port which will decrease velocity, but on a 347/351 and up the 185 will really feed the beast better. This is something you may want to consider.
