The ITR manifold will fit a b16, but not a GSR. Tell him he needs to go buy a clue before he gives people advice.

 

the bold pattern for the ITR is the same as an LS correct? if that is the case can the skunk2 manifold then just go on an ls head?

 

ok went to modacar.com and found the hondata gasket for an ls. They didn't say they make it on their web site but i guess they do.

The bolts might line up(not sure here) but I know it is a hell of a lot of work as in modifing the manifold with a dremel tool. My ex roommate tried installing a B16 manifold on his B18A1, it took some reshaping of the manifold. You'd be much better off just getting the Skunk2 for the LS.
