It's been awhile since I removed a cowl, but I don't recall there being any rivits that needed to be removed. With the gas tank removed I think there should only be 5 cowl to door pillar bolts to remove, assuming the 3 front body mounting bolts are out. There is one rivet near the 2 bottom most bolts that doesn't need to be removed as it's only holding the side reinforcement to the cowl panel. The very bottom of the cowl assembly slides under the subframe and they are commonly "stuck" together (and possibly a rivet here also - don't recall) - see attached picture. Good luck.
