>>For any serious power increases, their is no more head room with the stock
injectors, and with the unique central manifold location, no clear path to
larger injectors without some sort of custom manifold being created.  Their

Not exactly.  Scoggin-Dickey has been marketing a Vortec-compatible TPI 
upgrade base for years, and Holley has just released a Vortec version of 
their StealthRam which has already proven itself as being a great PFI/SFI 
intake on the gen I motors.  Both of these use "standard" PFI fuel 
injectors, and can be made to work with the newer style "small-body" 
injectors used on the LS1 cars and 5.3/6.0 trucks without much trouble.
