Lunati camshaft keyway/woodruff key?

I'd contact Lunati.
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!
First thing I did was call Lunati and received there typical response they share with so many other places. You know the line.

As to my machinist, why would he need an *** whooping?
As to why he can not kill the key down is he doesn't have the engine, I do. My machinist did the short block and that's it.

Oh, I normally assemble my own stuff. I'm just a bit shy on free space. That's why he got the short block job.
