Default GM head gasket 12558809 and 12558810

Is there a part number for just a kit that has these two gaskets or do I need to buy each gasket seperate?

Are those the graphite gaskets? I would contact Skoggins in the morning when they get back in. I just had an issue with my new cam plate and they were fully versed in the GM parts changes that were taking place.

Those are the individual gaskets....12558809 is the driver's side and 12558810 is the passenger side gasket IIRC.

Unless you have the older heads (00 or <) I would use the newer universal (One PN for both side) head gasket.

Use the metal (newer) gaskets. Graphite is a pain in the *** to remove.
