Not sure what you mean by cam cap bolts? Do you mean the cam top cover bolts which are chrome or the ones which hold the cam bearings in place under the cover?
Cam cover and cap bolts are the same. Kawasaki part number 92003-092 - m6 x45mm. Depending on year the bolts were either chrome, zinc plated and then black. Chrome usually on the earlier models. That goes for cover and cap bolts. And at 10ftlb max you aren't going to snap them anyway no matter what grade they are.
