don't respond to a block plate with most standard measuring equipment. You will not be able to measure any bore distortion.
As bore size decreases, 4.250, that same distortion would be all but entirely eliminated. Even when using the max size, 4.625, there would be about a .300 thick wall remaining. It would be next to impossible for a .437 fastener to make a difference.
All our blocks, regardless, receive the plate/gasket combination.
Have you ever had any of these blocks inspected on a PAT machine? Curious what the results would be (true cylindricity) with and without the plates, using the PAT machine.
