Well Crispin, don’t you think these “apparently knowledgeable sources” should declare from where they got their information? If it’s true, then why isn’t it in the comprehensive press release which you’ve quoted?
Mat; if you have both camshafts in stock could you measure it for us please?
No-one can conclude that the 190 camshaft has increased lift simply because it has a different part number.

The 180/190 cams have greater lift and a larger overlap than the ones fitted to the 177 Rover.
This is achieved by both a decrease in the lobe separation and an increase in the lobe height, I measured three sets of camshafts about five years back when I revived a very early commission number ZT190 that had suffered timing belt failure.
In addition, the static timing as provided by the camshaft front belt is different.
I hope this clarifies things a little
