I believe this is true. There were photos in one of the bike mags back in the day, and a statement from Kawasaki clarifying that the port work is done at the factory. This is doubly easy to understand while restoring the head on my '81 750E2 and seeing how crappy the casting and machine work was in the ports. The short side radius had a sharp edge where the port was cut to accept the valve seat, and excess material around the seat in the bowl area. I took a die grinder and smoothed out these sharp edges on my engine with only a minimum of work.

Some before and after photos...

It's just a slipper. It keeps the chain from slapping the cover. It does nothing to the chain tension. With the cams installed you can lay the over over the top of the head and the slipper block doesn't compress the chain.
