I need some new heads for my stang & not sure which one's to get. Thinking of the AFR 165's, Edelbrock or Twisted Wedge heads. I can't use anything with the 2.02 valves besides the TW's cuz I don't have my pistons notched. Which do you think would be the best with my set up? Also should I keep the E303 or get a custom cam? After evrything is installed I plan on having it tuned.
First of all I have a 306 w/ TRW forged pistons, E303, Typhoon Intake, 1.6 FMS ped mount, 70 TB, 73 mm C&L, 24lb injectors, 255 fuel pump, MSD set up, BBK shorties, MAC o/r x-pipe, bassani mufflers w/ dumps, T-5 w/ king cobra clutch, 3.55's, etc.........

Twisted wedges can't touch AFR's power gains. I say AFR's out of those three choices.

You will get many different opinions on this one. There are many AFR Fans and many Trick Flow fans...Here is my 2 cents:

Twisted Wedge Heads and the AFR 165 heads are about the same...see the flow chart below....The AFR 185 heads will make more power than the Twisted Wedge heads...maybe 20 or so....

Twisted Wedge versus the AFR 185s only 20 horse difference...

AFR 165 versus 185...the 185s made about 17 more horse than the 165s...

My vote is the Twisted Wedge Heads for your set up...save a few bucks...you can always port the Twisted Wedge Heads and then they will flow like this:
