Pics of what happens when a valve drops at approx 7K rpm
These pics are merely informative...no blame or some vendor sold an incorrect part. Also, this wasn't the stock LS7. The replacement will be a stock LS7.

I can guess that it was a simple keeper failure or a geometry issue...not sure. The only thing I'm sure of is a stock LS7, headers, and tune will be my next track setup.

Stephen, I have followed your posts for a while now and I'm really sorry to see you pulling another engine out of your Z/28. Keep the faith, man. This is a great car and you push 'em pretty hard...just like they were meant to be.
Good luck with the new engine. I will be following along.

Crap!
I was just about to do an intake, heads and a cam :( Is this a common occurrence?
