Ya know, I forgot to add, that if you do install an in-line filter, it might be a good idea to drive it around a bit without the thermostat to get maximum flow. Then after you've thoroughly dislodged everything and trapped it in the filter you can re-install the stat.

OK, thanks for everyone's input on the water jacket pressure question. I think Dave's experience with head gasket failure with water pressure at 30-40 psi will make me pull the thermostat and run the water through with the system "open". Following a good flushing, I will probably throw in an old radiator and do the "Cascade" cleaning. I do like the filter idea. Ken, will you share your info with the list regarding a source? Thanks again everyone for your help. I'll be back with more questions.
