Small block Valve stuck

I’ve seen plenty of toasted cams thru the years, but something I don’t recall seeing in years gone by is....... the lifters having chunks missing from the bottom of them.
This seems to be something that I’ve only seen over the last few years.

Yeah, we've all seen how crappy lifters are nowadays, this just cements it even further.

....and that's pronounced SEEmint down here. LOL
