The caps on there did not match up with the block but I’ve been unable to find a machine shop that can machine them so there’s a round hole for the crank.

I hate to ship a block to get this done before I have reassurances that they can make it work but does anyone know of that has successfully made main caps match the block? Given I’m spending a lot of time these days staying home and catching up on car projects in the shop I figured it would be a good time to start building the next engine.
