Any how the did a great job! My question is the took the entire rocker cradle apart and cleaned ever thing before they set all the valves.
Do I need to worry about it now since the manual says not to remove the black bolts?

Very reputable shop that specializes in cylinder heads.

To be honest I wouldn’t worry. I’ve purposely have done this to see what happened-nothing abnormal. Now here’s why, the black bolts circled in yellow essentially just hold the driveshaft-yes this what it’s called.. to the VVEL ladder, the black nut looking things are actually a point of adjustment for the intake valves controlling the actual lift of the valve (each nut controls 2 valves) think of it as a Throttle position adjustment screw-slight amounts can make big changes, they are set at the factory. If the valves were set correctly when the heads were put back together then I wouldn’t bat an eye about it. They probably marked where the nut was set before disassembly.
P.S. I also have the JWT C2 cams.
