ZX750A1 intake cam

I have a 83 zx750 (gpz)750, the intake cam broke can I substitute a zx750 turbo cam which also fits the KZ650 for the original from what I understand the non turbo gpz has higher lift and duration cams,,,or can I modify an ZX750A exhaust cam to be an intake cam

The 750 Turbo cams are KZ650 cams, so you'll slow your bike by using them.

People switch intake and exhaust cams all the time, so your exhaust cam ought to swap with no problem.
