KZ440 Camshaft help needed?

[Sebu]

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.

Web Camshafts seems to have a profile for the KZ440. I had them do a cam for my XS650 a number of years back.

The ports and valves on the KZ400/440s are more than large enough for all but the most extreme builds.
How much more power do you want?

I dont have any specific power number , just want the bike to be a bit more "sharp" and still be good to drive. thanks for the link. I also have a tiny turbo but I might let it sit in the garage since getting parts for kz440´s in Finland is quite difficult.
