Hey everyone, I have a '94 GSR that currently has b16 cams in it.(Read here for more info on that) It had type R cams in it when I bought the car, but after a "situation" I had to swap in the Si cams. Anyway, I know the car has dual valve springs on i/e, but I was wondering if I need to upgrade any other part of the valve train to put the type R cams back in? Or will my stock valves/retainers/etc. be ok? I don't really trust the previous owner's work, so that's why I am asking about the valvetrain. He seemed to like to cut corners..Anyway, thanks in advance for any info. I am hoping to do the swap this week.
