Align boring is usually reserved for something someone is going to be putting a large sum of money into. I have a machinist friend that does a lot of rebuilds. and even builds race engines for the local IMCA drivers in this area, and align boring is done very rarely, even on the big horse engines for the track. He rebuilt my 230 in the 64' and we didn't have it align bored, and I'm VERY happy with the way it's turned out. Made it's first real road trip last week down to OKC, and it ran perfectly.
Longbox said it best, you might want to do some more homework about who you want to do your build. Just my .02.
