I don't seem to have any steam ports.I thought I had a ls1 2 gen 2 design lm7.
After watching all your YouTube videos I am not sure what I have. If. It helps The head bolts were all medium length. A second question, can I eliminate the knock sensors? What do I need to do to eliminate them?

All LS based engines have steam lines as far as I'm aware. If all the head bolt lengths are the same, then it is a gen 2 LM7. Yes, you can if the engine is not going into an emissions-controlled vehicle like an old hot rod. Just get a valley cover without them and then program your ECU to ignore them. Thanks for watching!
