One word should answer your question.....the word "supposedly". Got any pics to share of it?
You can also try and find the block casting number and search online. The knock sensors should also be relocated to the side of the block. No longer under the intake manifold. If I recall you can still use the LS1 knock sensors under the intake during the swap so this may not be the best ID method if a LS1/LS6 valley cover was used.
