If you look at the pic in Photoshop where you can enlarge it, those holes are oval shaped where the pulley was beating on the bolts. Just me, but I would re-place the wheel, pulley, spacers (if it has one) and bolts. To me my life is more important than re-using a messed up wheel and pulley assembly, they can be re-placed easily, we on the other hand cannot!

RIGID makes a nice bolt remover kit, I think its about $40, it has a drill guide so you dont drill crooked, has correct bit for their splined extractor, and sleeve to remove with a wrench. You may have to apply some heat to melt the loctite, especially if you used red. Looking at your pics, using this kit with the guide will be a piece of cake.
Where you located in the bay area? I have the tool to remove these.

My take on this problem and fix
I know this is an old thread but this is a major safety item. This is right out of the HD 07 Touring parts book for the Bolt it is PN:3737A 7/16-14x2 1/4 hex head w/lockpatch (GRADE 5) and this next part is right out of the 07 Touring service manual "Apply two drops of Loctite High Strength Threadlocker 271 (red) to threads of each of five sprocket bolts. Secure sprocket to hub using bolts with flat washers (and locknuts on laced wheels). Tighten bolts to 55-65 ft-lbs (75-88 Nm)" The max torque for a 7/16-14 grade 5 bolt is 52 to 55 ft-lbs I believe. So they are being over torqued to begin with or torque to yield which must be replaced every time. So what I did was replaced mine with ARP stainless steel bolts and washers these are rated to 200,000 psi which is well over a Grade 9 bolt. Knock on wood I have not had a problem with them 30,000 miles on these bolts and about six tire changes pushing 111 hp and 113 ft-lbs torque to the rear wheel and I take my pulley sprocket off every time and use the same bolts when I go back together. I think if you measured the ones that loosened up you would find that they are stretched.
