header question
The bolt pattern for exhaust manifolds and headers on all b series engines are the same. I believe you have a b17 not sure thats just off the top of my head. Someone correct me if I'm wrong.
If I remember properly, the GSR header is different length. The GSR collector and flange sits further back than on an LS/GS/RS setup. If you swapped the rest of your exhaust then it would work...
