Man, you can over-complicate this.

Best you look up the dimensions of a bolt, any bolt. It is the major diameter of the bolt (or threaded hole) that you can't cut into.

Yes, this started with the hemi heads, but it affects everybody. The Chevy heads are right there as far as being cut.....have been for years.

Simple rule .
