I,ve done this for years just make sure all debree is cleaned from around piston rings move pistons up and down and wipe with clean cloths
As above, i also get all the pistons half way down the bores, cover the top of the block with masking tape then cut out the masking tape from around the bores. Bring the piston you are working on (or pistons on a 4 cyl) to the top and put rags down the other bores to prevent crap gettin down.
The masking tape will prevent crap gettin in the water and oil gallaries and also the head bolt holes.
