KZ440 Camshaft help needed?

I looking to find some specific info about performance camshaft for a kz440. Previous owner had swapped new valves and propably got the timing wrong.. Exhaust valves had made contact with pistons when starting up and both are bent. The head is now ported and waiting to be rebuilt but i noticed that the cam lobes are pretty worn out so I taught that I would get them refilled and on the same occasion maybe get more lift and degrees. The problem is that i dont have knowledge of this type of engine so any suggestion of the cam profile would be helpful. I have been tuning and playing with 2cv boxer engines but bike engines are something new for me so any help would be nice.

Have you checked Web Cams? They make cams for a wide cariety of vehicles.

Yes, and got specs for one. Does any one on forum had one?
