From what the picture shows, it is likely that the engine spun a rod bearing in that very cylinder. Hence the piston appears to be sitting a little below the deck. However, if all pistons seat equally below the deck surface may suggest that someone has been inside this engine before, lowered the compression by either using a various combination of pistons rods, crank - stroked it. In that case, you shall not experience piston to valve clearance issues, but will experience lower than normal compression (less power). However, if running a turbo, then I wouldn't even worry about it.
