Did you rub any copper grease on the threads of your new plugs?
Copper grease is a high adhesive lubricant and anti corrosion agent that can withstand high temperatures and prevents the spark plugs from seizing in the engine. I use the Wurth product and was pleased to see that my Rover Service Centre also uses a number of Wurth's products in their workshop - including copper grease.
I don't claim to be an expert, but have heard that some old plugs that have seen 100,000 kms service in the KV6 engine have been a "real B" to extract.
