So instead of gluing my case together and measuring bores, I glued & bolted together two gauge blocks (advertised as flat within .0002"). Measurements of the stacked blocks with and without the 574 were the same (same technique each time), down to .0001" resolution of my micrometer. The loctite was applied to one surface as thin as possible, I spread it with a gloved finger and wiped off all excess until just the thinnest possible layer possible remained on the surface.
I am not a machinist or an engineer, so I can't say if this is significant. Even if the clearance increased by .0001", I would not be bothered by it on my personal engine. I have no way to assess sheer resistance when bolted together. After 18hr cure time and unbolting the blocks it took 10 moderate blows with a rubber mallet to separate them. A small amount of the 574 on the surface was still uncured liquid and could be wiped off, most of it needed solvent to remove. There was no visible excess around the edges.
My pseudo-science exercise may not be applicable, but maybe by sharing an expert will further educate me

That's really interesting - thanks for reporting that. Can you describe what sort of clamp load you placed it under?
