I see Erik hasn't responded yet to your question so I thought I would offer up what I know.
The early KK,s did use WR valves. At some point in the production year they must have decided it wasn't working so good or just wasn't a good idea for some other reason and they went back to using standard K valves but kept the KK/KRM cams. I have never seen any documentation to show when or at what motor number they stopped using the WR valves and it has been a mystery to me for many years. My KK is serial # 2650 and it has the standard K valves. I have seen K cylinders with the WR valves in them but no Idea what the serial # was for the motor.
The KK valves picture is from the 1956 K parts book, the KK brochure picture is from an original KK sales brochure and the Competition Cam kit picture is from the 18489-53R "Special Roller Tappet Kit" that I posted earlier in this thread.
I am still very much looking forward to seeing the "flat tappet cam kit" bulletin.
