Here at my course in CO we have a similar situation. This past spring the newly hired superintendent and myself, a newly hired assistant, inherited a poorly maintained Toro Network 8000 system with an inefficient Site-Pro program and minimal record keeping. To remedy this course-wide irrigation inefficiency problem we essentially did an audit of every single head (approximately 1500 of them). We turned on each head individually, watched it run and made notes on the as-built next to the head as to what type of adjustment it needed, i.e.: replace nozzles, swap for a part circle head, etc... I guess I would recommend you do this prior to replacing all of the 670's because we had/still have a lot of them and in the right location do an adequate job. This could save you money to use somewhere else as opposed to replacing 670 regardless of how its functioning. It actually doesn't take as long as you might think. Doing this will get you an accurate number in regards to the products you need to order to make necessary changes/repairs.
In addition to that we documented man hours spent as well as cost of parts throughout this past season for all irrigation repairs and improvements. We then presented these records to our membership showing them the cost to maintain an outdated, inefficient system. The result is that we are currently working on a course master plan and a new irrigation system is one of the top priorities. Just my suggestion, hopefully you find it useful.
