I’m sure it’s been asked but I need help with removing valves

Patience is no joke. Being one not to give up, I gave it another hour and got ONE lower clip (#2 in my photos) and spring out. Wahoo! But #1 is still stuck. I saw a video where the guy mentioned using a drum brake spring tool (with hook on the end) and a slide hammer. I have both tools but need to come up with a clever way of attaching the two so I can slide hammer it out (unless that’s a bad idea?).
