1983 kz750-4 cam swap

What year GPZ750 cams would fit a 1983 kz750-4 LTD and is there any noticeable benefit?

83,84,85 and yes there would be a differnce also note GPZ750 used different base circle cams so be sure to adjust valve after install.

Note: the 1982 gpz cams will also fit, but they are not as aggressive of a profile.
Beware that the gpz750 turbo cams will fit, but are simply kz650 cams. You don’t want these!!

The 83-86 exhaust cams only will have a smaller base circle, so they will require thicker shims to set valve clearance.
