Default 2.5 head gasket differences
I'm looking for a pair of these and noticed that they differ from 2007 onwards. As my engine is an upgrade, how would I know if it is an early one or 2007 onwards.

The block cases are the same, its the head waterways that change after 06

This is a 06 onwards type, it has 4 individual waterways at the bottom, pre 06 has 2.

Thanks, I presume the lower part of the block would also have 4 waterways on a later head.

No, its the heads that are different, the blocks are all the same, always match the gasket to the heads fitted.
