Hi Jerry, I think these are early KK cams. My early book is missing, does it show the WR cams set -41? Early KK ran WR valve set up. WR is roller I believe. These are bushing axles. Came with boot followers in my first basket. 90. Just rediscovered them! Also 52K cams. And difference in #2 cam shoulder depth. K vs XL. Could you post these in the current cam thread? Still haven't got my phone photo figured out. Thank you Buddy. Erik
