Jerry,
Exactly my experience. Had to cut and reform that part of the cowling and
even then had to add reflective heat resistant tape to the inside of the
cowling to save the exhaust pipe burning through. You don't notice the
larger port bulge from the outside unless you know what you are looking for.
