Valve seal without pulling the head?

Any of you had any luck replacing valve seals without pulling the head to compress the spring? Needing to do them on both our bikes. Mine (the wife) 09 Fe450, & his 16 Fe501s (husky).
Basically looking to see if anyone has had success with the "on bike" spring compressors. If so, which 1's.

i thought the question above was kinda clear... but..... what did you use to compress the valve springs that would fit from a top side perspective on the 70 deg engine.
be the same general issue with the newer big bore bikes

I'd probably just pull the head instead of attempting to sneak them in
