I'd like to see what the current part numbers are too so I can see if that's what the dealer used for me.

What might be even better is a list of each generation of parts with their part numbers and the dates they were introduced. That might be a little too much work though!

The new revision gaskets were introduced on Oct 24, 2003. The new GM gaskets will have two metal pins in the gasket around the bolt hole closest to the coolant passage. The rubber o-ring part of the gasket will be black.

Gaskets with blue o-rings are the older design. Green is aftermarket.
