Should I run these cylinders?
Have a build on Saturday and am doing my final clean/prep/inspect of parts. Noticed a couple of flaws in 2 of the 6 reconditioned cylinders I got from EBS. In the first pic, there is one single flaw/pit in the cylinder. Easy to get a nail on it. On the second pic, second cylinder, there are several tiny little pits. Some can catch a fingernail but they're all really small.
All are in the travel path of the rings. Thoughts on pass/fail? 1st cylinder:  2nd cylinder:

Alright I slept on it, and was not at all comfortable running these. Called EBS and they're rushing a whole new set out to me. Very apologetic.

Has to do with porous castings... happens from time to time. I just redid a set of 356 alloy cylinders for a customer and two of them looked just like that. Had to junk them... EBS is really, really good. They take care of their customers extremely well (myself included!).
