Perhaps this is doable at 180* of TDC but you will still have to be carefull with the little valve keepers not moving out of place.
It really is quite easy to R&R the rocker shaft. With the valve cover off, I could change a shim in <10 min.
so those 4 top bolts out and the 2 cover caps (on the backside of the pic) and the rocker shafts pull out from the backside of what we see in the pic? rockers moved out the way & then
replace with the proper calculated shim and reassy? actually that seems very simple compared to some of the OHV jap stuff.
