The tapshifter at new england dragway I ran right into it in first and second gears. I wou,ldn't worry about either V-8. Chevy has been making these thinghs sinvce 1955y.

It seems lately valves are dropping.. The funny thing is I never heard of a 327, 350, or a 400 dropping valves over the years, but I'm sure some did..

I've got some friends that have plenty of LS motors and they have friends who work in dealerships in our area.. These are camaro guys, not you typical camaro guys, Some day we can meet up and I'll take you to visit them. I live in your area. Anyway to make a long story short, some pre 2010 camaro LS motors are dropping valves. That could be due to people tampering with them, not sure, or it could be due to weak valve springs letting the keepers come loose, bad valves or keepers. Who knows, but it does happen.

So the cure would be if you did have your 2010 apart for some other reason like say putting on a blower, then taking the heads off and throwing in better valves, keepers, and springs.. That aside what would a person doing this replace the stock ones with ?
