i'm trying to track down the part numbers for the two intakes.

i'm searching for an LS6 for my z and don't want to get scammed. cause i know the LS1 intake from the vette didn't have the EGR.

i found the part number for the LS6 being 88894339

where on the intake can this number be found? or is there another that i should be looking for?

i can't find a part number for the LS1 intakes. looking at an auction on ebay i found a picture with the number 12556333 stamped in the intake, but this doesn't correlate to any pn i can find.

any help would be appreciated. maybe a DEFINITIVE way to tell the difference between the Fbody LS1 intake, Ybody LS1 intake and the LS6 intake.
(i already know the fbody has the egr provision).
