"It sounds like you've put one of these non-vented caps on an earlier (pre-'71) car. Have you had any problems with your cap leaking fuel to the outside due to these grooves (barring the occasional overfilling of course)?"
No.
Did you make the grooves in the gasket concentric (circles), or radiating lines? How many and how deep?
I didn't make them myself, the cap came with the car purchased in l981. Four radial grooves are cut in the gasket, V-shaped and to about half the thickness of the gasket. A single one would probably do fine, all it has to do is let air in at the rate gasoline is removed from the tank, which if you take for example 20MPG at 60MPH is three gallons an hour. Looking at my gasket I see that is stiffened some and developing some age cracks. If you need to replace yours be sure to get a rubber compound that is impervious to gasoline.
