2001 LS1 intake same as LS6?
You can tell which one you have because the older LS1 intake's part# is on passenger side where the Z06 type is on the drivers side.
Their shipping will get you everytime 
Glenn Honestly, I don't remember if they discussed if there were different part numbers, but that would not surprise me since GM has done this for years. It even made an industry for cross reference manuals.
Hope this helps.
