Lunati camshaft keyway/woodruff key?

I'd contact Lunati. I have their 10200701 hydraulic flat tappet cam in my 318, and I am quite happy with it. I just used the woodruff key out of my old cam, and it fit perfectly... As to your machinist, why the hell can't he mill a little off the end(s) so it would fit? Sounds like he needs an asswhipping!
