hmm, which heads to go with

By next summer, I'll be replacing my heads, so I want to hear what you guys think would be my best bet.

So far I've read about GT40P, GT40X, TFS Track Heat, and TFS Twisted Wedge.

Right now I'm running an E-cam and TFS street heat intake. And just so you know, I prefer down-low torque over top end horsepower. (for example, i'd rather gain 15hp/30tq than 30hp/15tq)
 
Its hard to beat the low end of the stock setup. I will say that I didn't lose any low end. But, I didn't feel a gain down low in the RPMs either from the new heads. If you need to feel low end then steep gears are the ticket. I really wish I had gone with 4.10s now. As with all my mods to date I picked parts that won't hurt streetability since it is a daily driver.
