yep as above main thing is to make sure every bit of junk etc is cleaned out from everywere you can do this with pipe cleaners for parts such as camshaft crank etc the block does have allan bolt caps on oil ways and water i think if u can get them out with a bit heat and when block is bare on a nice day a trip to petrol station jet wash blast it all out best you can then dry it off with oil towels quick spray over with wd40 in bores etc stops any rust startn and away you go putting it back together lol
