Looks like the rockers are on shafts and would be removed the same way as most other rockers, pull the shaft out the side after removing the retaining bolts. I don't get why there are 2 retaining bolts on each shaft though, instead of just 1?
I'd bet this uses cupped shims over the tops of the valve stems. You wouldn't want those to bear on the valve springs themselves.
