When replacing valve stem seals, I do not need to take the heads off. I use regulated compressed air to pump into tne cylinders to keep the valves closed when removing the valve springs and replacing the valve seals.
You would need some specially fabricate tools for the job.
1. A connector to be screwed onto the plug holes for the compressed air.
2. A special leverage tool for compressing the valve springs. This item might be available at some tools outlets.
Maybe you can check around to see if any shops have the tools and performs such replacements. It would save a lot of headache, time and parts cost.
