you would want the 807HPN
no need for dowel hole, that is for doweled aftermarket rods. Endurance race and circle track stuff sometimes use dowels to keep bearing from spinning even when they are torn up.

the HP series is fine for stock cranks, and N stands for narrow. You don't really need the narrow since your crank doesn't have large fillet radius. But they will work just fine, and the HP / XP series only come in Narrow.

the 807SI are a stock replacement cheap bearing (aluminum). They will work yes...but I've found the HP series to give better clearances and just look like a much better bearing.
If the 807HPN give you too wide or too tight of clearance, they are also available in +/-001 sizing.

807HPNSTDX part no. is +001 extra clearance
807HPN 001 part no. is -001 tighter clearance

I've used these a lot for stock cranks, they work great. I keep all 3 sets around STD, STDX, and 001 so I can set clearance exactly what I need. You can mix half shells to tighten or loosen up in .0005" steps as well.
