Your LS motor is not much different than 94-01 LS's. Most of the changed are in the ECU.
Any cam for a B18B1, B18A1, and B20 will fit.
Crower and Brian Crower makes cams for this motor. JG also does, though it may take you some added searching on those. Crane used to make non-vtec cams, but went bankrupt and sold all of their stock. Another company has picked up where they left off, but they are a bit behind the game.
Pretty sure those are the only manufacturers.
