Land Rover have redesigned the K series 1.8 head gasket and upgraded the lower rail that the head bolts screw into.
The head gasket has lost it's elastomeric beads and now has a laminated type of construction and the lower rail is beefed up - it must have an effect upon the clamping load. Head torque figures remain unchanged.

I thought all Land Rover K's were supplied by PowerTrain, if so why did these changes not make it into MGR cars? Have LR been stripping the engines down and modifying them after delivery? Where are LR sourcing there K engines from now if they're still being used?
I don't know what's happening supply-wise at the moment, but LR have to look after the owners of Freelanders with the K Series - hence the redesign. Quite who has done the redesign work is beyond me - it must be LR themselves?
Well it was said recently (either on here or keith's site) by an ex-employee that PT knew exactly what was needed to stop the head gasket problems, but the P4 weren't interested in spending the money. I wonder if this knowledge has made it over to LR?
This is good news anyway, for TF owners in particular.
