This car doesn't seem to be giving up much torque down low? Maybe we have different opinions on what good tq numbers are, but I'd be happy with this setup. Mods are:
TrickFlow TFS 225cc Cylinder Heads (64cc)
Vengeance Racing VRX5 (236/238)
Kooks Longtubes w catted connection pipes
FAST 90 Ported by Vengeance
Pulley
Corsa Catback
180* Stat

I do not want to get into a bashing contest, but the dyno at Vengeance has been rumored to read higher numbers that the average dynojet.
I think that SPIN is referring to is that your TQ curve is "peaky". Fo instance, you are not making 400 RWTQ until about 4.300 RPM, versus other set-ups that would make about that much around 2000 - 2500 RPM. Don't get me wrong TFS heads are great, but it depends what you are going after. Do you want a car to track and highway rolls at higher RPM's, or more TQ down low?

10-4 on Gunnar being the man at customer service. He has hooked me up with several pairs of heads through the shop that I worked at.

Yeah Gunnar is a great guy, I used their ls6 style heads on my c5 too! Actually TEA has the HS rockers for 350 if you get heads through them, just an FYI. Thanks everyone for their input so far. I'm not bashing or taking offense at all as I want info both good and bad, I'm always open minded. I guess since I road race, etc. I'm more interested in top end. Don't get me wrong, I don't want to give up all my low end tq, but 400+ below 2k isn't all that useful to me as I don't race stoplight to stoplight. I had a 10 second lightning so I know all about torque 
.... plus maybe now my tires will live a bit longer, hehe.

Oh cool, actually my brother lives in Fresno so I'm down that way quite often. What did you replace the vette with if you don't mind me asking?
I mostly road race but I do make it out to the track once in awhile, however with the 100+ summers here I'm not going anytime soon. I hope to have some numbers once the fall weather hits though.
