head??

I wanted to upgrade my head. I want to buy stage 3 skunk 2 cams, ferea valves, but the titanium retainers and dual valve springs i don't know which ones would be good. does anyone know of a 99 gsr head set up?

you can always go with spoon or mugen head, but those are really expensive.

Try going about finding a CTR or ITR head. The CTR is pretty damn hard to come about but the ITR is a LITTLE easier but not by much. Then you would have a pretty damn good setup and it would be stock too.
