DACK, I was able to dig this up..

The media is 20/30 SAE or 0.45-0.80mm walnut shells that can be sourced locally

Marco marcousa.com/index.cfm or www.trinco.com or www.mcmaster.com

Here are the instructions ( disreguard the N73 instructions as its the same for all engines )

BTW the "dirty" valves shown in this guide are no where near the really bad stuff that i have seen .. im talking chunks ...
