Well, I need a new header for my Civic with a GSR bottom end and B16 head. I know that the SI header and GSR will mount up to the head, but I was wondering if because the GSR has something like a 34mm longer block than the si, if I wouldn't be able to get the SI header. I am looking at a greddy header for 280$, so I would really like to be able to fit the SI header on my engine. Any help would be appreciated.
Thanks
Ian
