Edelbrock 2.055 (30 degree back-cut) testing

I'm referring to a standard old school basic stock valve job. The only way to get the correct seat width, is with a 3 angle (or more) cut.

I agree, but you don’t have to use a 15 degree difference to correct the seat width. You can use 8 or 10 degrees.

But with a stone it’s a bit of a ***** to get all the cuts the same width.

That’s why I prefer do to my valve jobs with a forming tool.
