Looking For 06 Duramax Head Gaskets


Looking for a certain type of head gasket for a 2006 Duramax Diesel. In 2006 1/2 model year DMax introduced a second generation head gasket design that is now the replacement for all model Duramax engines from 2001-2011. To my knowledge the first generation head gasket is no longer manufactured. My engine is a 2006 and had the first generation head gasket design installed from factory. Normally using the second generation head gasket design on 2001-2006 is no issue. My problem is the first generation design lasted 400,000kms and has worn/corroded a slight 'picture' of itself on the deck of the block. This picture is too deep into the deck of the block to mill the deck to clean it up. If I could find the first generation head gaskets they would seal up perfectly as it would lay exactly on the 'picture' that is on the block. I've tried all the auto parts stores in town, GM, specialty diesel shops, etc. Has anyone had the same issue and/or would anyone know where I could possibly locate a set of these first generation head gaskets in grade C?

**I've included some pictures to see the difference in design of the gaskets. The first generation has a crimped ring to seal up around the combustion chamber, the second design does not. You can see the crimped ring has worn a groove on the deck of the block. This worn groove is approx 1/4'' out from cylinder wall. The second generation head gasket is designed with a ridge that seals right at this 1/4'' out from the cylinder.

Thanks for your help.
