LT6916: Actually ITR heads are PR3-x(x=1-4). Same as B16 casting. You can tell if it's a GS-R hear easily enough though. Intake manifold is different (but easy to swap) also of course..

Typerguy18: No they are not. Not B series DOHC VTEC anyways (maybe B16A is diff but I highly, highly, highly doubt it..). Perhaps you are talking about LS valve covers or something but that's not the only black valve cover.
