go to a boneyard and strip all the brackets off of a junker sbc and make some templates out of cardboard so you know where you have to drill and tap your heads. just dont hit any water jackets.

You can't drill & tap them, there's nothing there to drill, only the thin casting wall (about 3/16" thick). There's no bolt boss like the right heads would have, and the surface of the head is about ¼" too far rearward anyway. And since there's only ¼" of room, there's no way to make brackets to fake it either.
This is why we all told you not to buy those heads when you first asked: we've all been fighting this same issue for the last 30 years now, and if there was a reliable way to make it work, you wouldn't be seeing the no-bolt-hole heads for so cheap.

I never figured out how to mount my a/c compressor, so as it sits I don't have AC until I dump my junk 461 heads. 
For the alternator, I ran it without the head bracket for a while with no problems, but a couple years ago I went junk-yard shopping and took all the tubular brackets and braces I could find. I got one that was around the right size, and I bent it to go from the back of the alternator pivot bolt to the header bolt. I've put well over 10k miles on it and I haven't thrown a single belt yet.

I'd be interested in seeing that link... I couldn't find it by searching... I'd like to see how that's going to work, considering the realities of the situation

I had the same problem...I got the brackets for the power steering....at the jy....I deleted the ac....with a little luck and a shim here and a shim there..and a real tight bolt...you can make it work....I used the stock ac bracket, only part of it, attached it to the first header bolt hole, using a stud instead of a bolt, I held the bracket on with a nut..then shimmed it out to align the belt...tightened it up real tight......no problem since......You can do it.

No. It's just 1 rod that goes from a header bolt to the back of the alternator. Nothing too special.
Their is a company that makes a one peice bracket for a sbc (tpi serpintine set up) its made up of alluminum casting and uses only the bolts on the block . but the cool thing about it is that it made to bring all of the accessorys closer together top to bottem right to left and its very clean looking peice. It was made for street rods using tpi set ups. It was in last months chevy high performance aprils issue. Its made by vintage air, 1-512-654-7171 or 1-800-to-cool-u. I believe its takes a special alternator for becouse of the way it attaches but the sell it too.

i have a set of 461 double hump heads, i have heard over and over about how these heads wont accept late style alternators. the heads i have has the bolt hole brazed in it. this accepts the alternator, but there are no other holes for A/C. i dont know if thats possible or not. if worse comes to worse, you can always weld the bracket to the head. lol.
