Where is TSP's back to back to back head comparison??
 

Does anybody remember TSP talking about flowing several different sets of heads (AFR, Dart, PRC LS6, etc) and swapping them onto the same car and getting dyno results for each set? I figured it shoulda been done by now or at least creeping up on the test date. I'm still shopping for heads and would like to see the differences in each one. If it's not already on the list TSP, try out the ET 215 you all carry as well!! I've been leaning towards them!

<----------Very curious as well!

Well I can tell you they are probably right there on the edge of this coming out, I have called a ton over the last couple weeks on my head deal with Jason, and they are in the machine shop/engine dyno a lot, so they are defintiely working on something big :) They are very busy, so we'll see what they are up to soon I guess.

I bet it never happens. And if it does, the results will hardly be valid on their dyno. To do it the correct way, heads should be sent to an impartial shop to do the comparo.

Yeah ... been wondering myself. I agree with the numbers thing ... would be more interested in seeing track times ... they can't fudge those.
