Nope. Most 799s top cut on valve job is 1/2 of a 243s or non existennt. Now where near what it should of been or what the 243s is. Why. I would imagine production tolerances. Cutter only comes doen so far. And if the material isnt there. It does not get cut.
And that cut is important. How can that be.its called mass production. Out the door it goes. I would not pay the same for 799s as i would 243s. (I would cause i have tooling to fix) but avergage guy shouldn't

 

799’s cast in Mexico, 243’s cast in Canada? Fact or fiction?

 

I think you're right about the 799's, not sure on 243's... but could easily be.
