From what I have seen and a few people I have talked to the LS1 seems to be more responsive to the pulley than the LT1.
I would go with the ASP pulley, it is a high quality peice. I had the pulleys on my 93 Formula and they really didn't do a whole lot. The gas mileage was a little better, and the torque picked up a bit, but nothing huge. With the LS1's the gains are supposed to be more noticable.
This will probably be one of my next mods.99 TA "RBLUTA" - NBM, M6, Whisper Lid, SLP Fan Switch, 160* Thermo, SLP LM, BMR STB & LCA's.

The LS1 produces a more significant gain than the LT1 because the LS1 has a belt-driven water pump. LT1 water pump is driven off the timing gears.Fred
