me and my frend was assembling my bottom end, and we got the crank in and the mains torqued down to spec. The mains were all plasti-gauged at .002 tolerance. Right about where the book says they should be. The crank was ground .010 and real nice and smooth to the touch after it came back from balancing.
We put the pistons in and spun the motor over a bunch of times by hand. All the main and rod bearings were well oiled, and the motor turned very smoothly. after we got dun cheeking how much the pistons where in the hole We pulled off the main caps and yanked the crank back out and this is what we saw.

the block was line honed too

Is this normal? These marks don't seem deep at all. You cant really feel them or snag a fingernail on them. It just looked a little odd. Is this anything to worry about?
