I've seen guys have a block completely mag tested, passed okay . . . then they spent thousands on machine work, assembly, etc.. Then, when they started it . . . water was pouring out one of the exhaust ports! Yikes - end of engine!
This is why pressure testing is a very valuable step in the build process. Visual inspections and magnafluxing can't "see" into all the places that cracks can appear!
