I got this at harbor freight. It actually works pretty good using the HB walnut shells. Use the 24 grint and not the 12. The 12 will plug everything up.

I can find the gun I have listed , but if you have a pretty good compressor then (90+ psi) then it should work pretty well. I even used it on removing the carbon from the tops of the pistons. The walnut shells dont do any damage to the aluminium; it is prtty mild and so where near as abrasive as sandblasting.
Once I was setup it took about 1-2 minutes per chamber.
Now for some Harbor Freight spot media blasting (walnut shells)
Looks pretty good but I still have to get the valves out and do under the valves.
Worked great cleaning out the exhaust runners as well.
