Gpz cams on a kz550?

Guys, just thinking out loud, a little curious about something.. I have an 82 kz550 a3, and looking thru these posts for months and months ive seen that people use gpz cams.. So for my bike, would gpz cams be a direct bolt on? And what yr, model cams would i look for? Annnnd, what kind of horsepower gains,etc?

I have a set of GPZ550 cams you can have for the postage. A while back I picked up a GPZ engine for the trans but you can have the cams.

Mark, I will keep that in mind, thank you! Is it a direct bolt on? Same motor, different cams? More lift? By the way, i just saw your post in projects, beautiful rebuild.. What i would give to live next door to you!! lol
