Cams run directly in the heads don't they?

If it's anything like a normal (car) OHC engine then the cams lift the rockers which depress the valves - all in the head. At no time is there any friction with aluminium parts. I seem to remember something about desmodromic(?) valvegear working differently though.

In the SV the cams run on the buckets, which depress the valves, no rockers. But the principle's the same, I think both parts are steel.
