Or an over-run of mufflers with a larger flange!!! Lol.  I worked on a P100 that had a 1/4" grove cast into the top of the exhaust port roof/cylinder plating. It was oem, never learned the reason why Partner did this but is suspect it was to start the  blowdown event earlier while still maintaining the torque associated with low exhaust height...
