I have noticed that IDParts has a 15% off sale on KJ CRD Head Gasket Kits, and Cam shaft Replacement kits.

These prices seem very cost effective for Oz owners. These kits should be perfect for any of the late model KJ CRDs (definitely 2005-2007 years, and possibly for earlier 2.8L CRD models.
The Cam kits include the two Cam shafts, lifters, etc.
Just a note on CRD Head Gaskets, there were three different thicknesses used on late model CRD heads, you would need to insure you buy the correct one for your vehicle. The gasket type is designated on a tab of the gasket that sticks out at the rear side end of the gasket. On this identification tab, a number of holes were punched, from zero, 1, or 2 holes. There is an example photo on the IDParts web link above. The order form asks you to pick the correct one for your CRD.
The Head Gasket kit includes new bolts, and an option to upgrade to ARP bolts, which are reusable for any future tear downs.
