I think the deal is the fast adapters were designed for fast intakes. The top side adapters leave a OEM fit into a stock intake and raising the bottom side of the injector would affect the injector spray pattern into the intake IMO.

Did you ever figure this out? Did you just use the orings off of the stock NNBS injectors on the bottom of the LS3 injectors?
