Ease up, RA. This is supposed to be fun, remember? I've never seen this question before, but I can tell you this: It's okay to mix blocks that have different pressure ratings as long you a) Have enough overall head to keep coolant running a a good clip, or b) Place more restrictive blocks up stream of the less restrictive ones. If you're interested in smaller diameter tubing as the basis of your water-cooling system both of these things are going to be more difficult due to an overall decrease in flow.
