And there isn’t a good way to hold the valves up when you go to reinstall the retainers. Could make sure the piston is at top of stroke and then you won’t lose a valve.

there is a proper procedure and proper spring compressor on quickserv describing how to do it without loosing a valve... and yeas, it requires the piston be at TDC when you do it.
