Heres what (I) do.

I take my blocks to the machine shop before I do anything.

Then they determine for me what it needs. Also what all the other parts need aswell.

Look at the ridge. That will give you a general idea of what the shop will want to do. When I buy blocks, I use that as a guidline.

It might need a hone, a bore or the garbage can. Let them figure it out.
