What are the best Mopar heads?

Stock there are only marginal flow differences between all the common four barrel heads-unless you spend extra for a ta or x head and you could easily beat there flow numbers with a little work on any smog 360 or j head.A bowl hog and blend and a stock head will make great power on the cheap.

Aha! You have fallen in to the spiders web! You are correct that the flow differences are minimal taking into account valve sizes, but note that I said "with the most potential"! The T/A heads have offset rockers with relocated pushrods similiar to the W2's. Even though the pushrod pinch still exists, it can be completely ground out. I don't see how any other factory head that came bolted on a small block from the factory could be as extensively ported as the T/A's.
