Simon,

Aren't your running a vortech? With forced induction there is no need to run headers (normally) because the headers work on a scavenging principle and wave mechanics. They help create a suction on the cylinder that actually helps draw more air in the intake charge due to the intake and exhaust valve overlap. With the blower you are forcing the charge in which also forces the exhaust out when the valves are open in the overlap period.
The gutted manifolds will get rid of the restrictive cats in the stock manifolds and should work very well with the blower. As far as down low torque, that is a problem with a centrifugal force blower, perhaps you can change pulleys so the boost comes on quicker and then bypass the excess boost that you are developing.
Better yet, change the pulleys, up the boost, then get one of those water to air intercoolers from the streetflight turbo kit and stick it in there.
The other option that I highly reccomend is to use a small nitrous shot for the cooling effect that it has. With a nice kit, you could tailor it so that it gives a larger shot of nitrous at low boost (for added low-end torque) and then reduces it as the boost climbs. Combine that with the aquamist or the water/air intercooler to control detonation and you are in business.

Bnoon also optimized my manifolds and opened them up a little and smoothed out all the old flacking. They looked great and there is no way I would spend $700 for vortec spec headers over these modified manifolds. I do however have the MSDS Y-pipe
