stanley blade does the job well enough. dont use anything abrasive as you will be taking small uneven amount of material off. once all the stuff has been scrapped off you can use a long file wrapped in very fine say 800 grit linishing paper, use even long strokes across the top of the block. usually run diagonally. dont apply too much pressure when doing this. just enough to clean the rest of the crud off.

if its a bare block then dont worry. just flush it all out before putting it back together. but if its still in the car, with sump and oil etc. then yes. block oil galleries. the water galleries arent as critical but you dont want any large chunks getting in there that you cant flush out once you do a cooling system flush before running the engine.
but you'd be a fool not to flush and change the oil as well.

another trick is to get a really wide bandsaw blade and grind it down so it has a sharp edge.
wrap the handle in cloth and duct tape and voila you have a nice scraper. we make them all the time at work as we have the spare parts lying about.
if not buy a razor blade scraper from paint shops or hardware shops. its pretty much a long stick that holds a razor blade.
might wanna stuff some rags or something down the cylinders so nothing gets down in there.
i bought this gasket removal stuff which helped getting really thick subborn bits off a gearbox paper gasket. though i'm not sure if it would effect anything if it got into your oil or coolant. stuff reacted with the rubber gloves i was wearing and was burning my hands

when i did myn i used a industrial vaccum(one used for sucking up broken pieces of brick)or just use a normal house one.then i blew all the gallerys out with a compressor.it work a treat and never had any problems.
