Seth, trust me, you do not want to start a TW vesus AFR head debate... you remember the thumper post right... this debate will be even worse. You are the search KING on stangnet, there has to be at least a dozen threads on AFR versus TW. I will not go into it because I do not care to be involved with the flame fest that will ensue.
But since you asked me, I wouldn't put anything besides AFR's on my car. The 165 is perfect for a 302 cubed motor. On a stroker the AFR185 is the better choice. I'm 90% positive that you can not run the AFR185 on the stock shortblock due to its 2.02" intake valve. I say 90% because I have read of guys putting them on and getting away with it, but I know AFR says they won't fit. Your car is heavy, so your mods should concentrate on how to make the most power and torque possible. You're already off to a good start with the long tubes and such. I, like Charlie, think you need to look at your plans as a combo and think about the cam now. Its so much easier to do a cam swap with the stuff already off to do a headswap. You know who I prefer when it comes to cams and such too... Ed C. Feel free to ask me any question you want on this matter, but I won't get into the TW versus AFR debate... its a topic that has been murdered here.
