can anyone recommend a good set of brushes for cleaning b series oil and coolant passages? im picking up my block this week from the machine shop and I will be cleaning it through and through. I have searched for specific sizes I may need and turned up nothing. I know goodson makes a kit for like 40 bucks, with 10 brushes. moroso also has a similar kit. not sure if the sizes I need are in those kits. also as far as brush material: is nylon a good option? seems like most of the kits are nylon, but wasn't sure what was actually best to use. thanks guys.

I just use a little cheapy kit from harbor freight. Its has 3 types of brushes (brass, nylon, and stainless steel I believe). The nylon works fine. I suppose brass or stainless would also work, but its not really needed. The passages shouldn't need that aggressive of a cleaning. my 2 cents.
