It's nice to see a conclusion to a problem. Thanks for following through the whole project! Nice work!

You might take up any offers on a used/good clip. At least you'll know what the steel is made from.

I'd probably wonder why the clip failed. They are hard to get out on most engines in normal settings. Guides are stationary. Repeated valve sticking putting force on guide movement (there is only force from the spring, nothing from a sticky valve would force a 40/60lbs spring down to release the clip to let a 1/8" gap horseshoe to pop out), spring pressure? not installed correct previously, or a bent valve. Maybe look at how it happened also in conjugation to replacing the culprit.
