It's possible but tricky to flip the rockers vertical as you lift the shafts/caps, if you have enough finger spread for one hand on each side. I've done it that way, but the glove fingers are much easier. Loosen the cap bolts first.

Another hint. Do not fully loosen any bolt. About three turns on each, then repeat, to let the shaft rise evenly against the valve spring pressure. Possible to bend a rocker shaft or bolt, especially the end ones.
