Maybe they are CNC ported from GM lol!
#561 castings,120k miles , time to rebuild , anyway less material to remove.

Yes its probable the valve seat cutter,but im amazed that it passed inspection.
I took off the heads 5 years ago when i rebuilt and did a h/c swap.
Before that it had a hard life on California Speedway between 97-03.
I have no stock track times or dyno so i dont really know?
But my car were fast as my friends lt1 so dont think the bad port job was anny
big issue.
