I’ve align bored and align honed hundreds of blocks. An align hone, properly performed, straightens the main saddle alignment. I have seen few blocks that couldn’t use a good align hone. Iron distorts over forty years of heating and cooling cycles.

Ditto....

I don't understand why someone wouldn't want to at least check the alignment of the mains, all of your block work is based off that. Why worry about decking the block and attempting to square things up if you aren't going to bother with align honing the mains along with that.....

I've never had a 50 year old block that "didn't" need an align hone and haven't met a machinist yet that didn't recommend getting it done.

But you really need a good machinist.
