I am NOT! reccomending that you do this.It has been done both very successfully and very NOT. There is some way of determining just which of those heads without the threaded holes in the ends can easily be drilled and tapped.I don't know it..nor do I know who does? Perhaps someone here does.It must have something do to with obscure casting marks.There have indeed been identical heads..except that one set was factory tapped and one wasn't.I THINK..pretty sure.. that some truck(light duty) used a 1.94 valve and had the heads tapped while the identical passenger head wasn't tapped but could be. There used to be some mention of it by application in old Hollanders..that the head was tapped for accessory holes.
There are also some different alternator brackets..as well as other brackets that were used with larger alternators and other stuff on med duty sbc trucks.

I hope I don't have to go to that extreme to get this to work! There are several great ideas here. I think I'm gonna try the one that mounts the alt off the header and outboard of the VC. Looks like the best & cheapest solution.
