If you have a set, look for #6.

I'm not in the shop right now, but I'm pretty sure my Cleaveland set of #6 screw dimple dies are marked as a #28.

Not sure what the Cleaveland set (my favorite dies by far but they're in a hangar) says but here's one from Brown Tool:

Simple way to check your current dies for the #6 screw head size:

Drill a #27 hole in scrap, find the largest die which has a tip that fits in the hole, and there you are! Make a few test dimples in that scrap and check screw head fit. A "too small" dimple die set won't make a deep enough dimple for the screw head (of course make sure it's an aircraft screw with 100 degree countersink angle, from your kit). And a "too big" dimple die set won't fit the correct hole size.

For #8 screw do the same with #19 drill size.
