Lunati camshaft keyway/woodruff key?

Carl, thanks for the tip. I am a bit rusty since I haven't done an engine in 15 years. Old hat fits a little loose. (LOL!)

I have not had a Lunati cam before nor have I opened up a Magnum engine for a cam change. About 7 or so years ago, I did a timing chain replacement on one but failed to take not of what that cam snout looked like.

The hardware store keys held up under stress OK? I did find stainless steel keys. I'd rather a stronger steel. I don't want to sheer the key. While it isn't under a boat load of stress, it does see a good bit of it.
