It?s my understanding some of the 1996 and newer Disco?s had issues with sticky exhaust valves which can cause momentary loss of power/engine stagger. The sticky valves results from carbon build up on the exhaust valve (see link to article below for details).

At some point, I?ll be taking the heads off my 1996 D1 to replace the head gasket and perform a complete valve job. If I have the older style exhaust valves, I will be installing the carbon cutting exhaust valves.
Anybody know which year or particular VIN #?s when Land Rover began fitting the Discos with the ?newer? style carbon cutting exhaust valves (see pics of the older and newer valves)? I want to order the necessary parts before I start taking the engine apart.
