I have a ZZP VS cam setup on my 97 gtp. It's strong and works great, but I see 2 degrees of KR up top every now and then that I wanna get rid of. I know that rockers help reduce KR and they start to kick in once you approach the higher revs. I am pondering a good set of 1.6 or 1.7's. Will I see a drop in KR up top with some slightly higher ratio rockers. I dont have a ported or bigger throttle body. Maybe that will help out more than the rockers? I also need an Idea of the power I might gain.

I think my mods are in my signature, but its XS headers, vs cam, no res, Open Cone intake, 3.3 pulley 104's and 180 t stat tune ect.
