Does anybody have a good way of cleaning the water passages in blocks/heads? Given that the bores in my block are very good any chemical methods mustn't damage them. Also since it's a early block (screw in core plugs) I'd rather not disturb the core plugs since I gather that replacements are unobtainable. Any good ideas welcomed!
