The vise grip method was my brainchild.... it works flawlessly, assuming of course you actually pay attention to what you're doing! In any case, I removed all of my smog gear, I went with the idler bracket from ford. The belt routing diagram above isn't quite right since the tensioner is in a different place.
The cheapest thing to do about the smog holes in the back of the heads, it to cut the existing little blocks off their lines, then simply weld the holes closed and bolt them back on. A machine shop won't charge you more than $10 for doing this. The hardest part is getting back there to take them off and put them back on, luckily for me, I had the engine yanked when I decided to do this.
Hope it helps
