Yep, valve guide seals. IDK if there's room to do the work without pulling the head. If you try, get or make a air fitting to fit the spark plug hole. I've taken a old spark plug, break out the ceramic and weld/braze a air fitting to it. Pressurizing the cylinder will hold the valves closed after the cam is out and you remove the valve keepers. Or, pull the head and I've use a standard, full size compressor on 700's. Speaking of 700's, I found the casting where the seal mounts is easily broken off. Just be careful. If you pull the head, I would at least lap the valves.
