I am in the midst of building a 347 stroker motor and am wondering which heads to go with. i currently am running a trick flow track heat upper and lower intake manifold and am wondering whether to stick with trick flow and go with teh twisted wedge heads or the afr heads. i know there is a diff in cost with the afr heads being more expensive but want to kwno which ones woudl give me more hp but still making the car streatable. i have ordered an Eagle forged kit and a pretty big cam from comp. pleas respond because i need to order soon. thank you every one
