The "bit that goes on the valve" is a lash cap. Typically these are not found on Nortons, but are sometimes used. The use of these will affect the geometry, sometimes necessitating shortening the pushrod. (Note: If buying new valves Commando valves have a longer stem than Atlas/P11/N15). I highly suggest washing the newly blasted head with Dawn dish liquid in enough hot water to totally immerse the head. I use spiral brushes to thoroughly clean the pushrod tunnels and a length of 'pipe cleaner' to scrub the oil drain holes. I like to do this twice, rinsing with clear water and compressed air after each wash. Most auto supply houses can supply the brushes.
It’s a glass media for the abrasive. Soapy water would get it clean, but not as good of a finish. I haven’t been working on it lately. Have a lot of life things going on at the moment, but should be getting back to it soon!
Combat head ('72 750) and RH6 ('73 750) also used 32 X 32 mm inlet stubs and Amal 932 (32 mm) carburetors.
Thanks!

Solid suggestions! I will find some brushes. I already ordered new valves, as I don’t want to deal with the unknown.
^_^ You ain't homeless... You can sleep in the vapor blaster cabinet!! 😅 Spoiled! That's awesome... Wish I had one...
😂😂 nearly could! Thanks. I absolutely love having it
@@motohomeless9168 Thx for the inspiration to actually work on my own Commando :-D It's on the list! Work safe my man.
Absolutely! Where are you located?
@@motohomeless9168 San Luis Obispo CA. With the Commando- the bike I never thought I would own...
Nice! Other side of the country from me
What is/was the media in the vapor blaster? Wouldn't a soapy pressure washer achieve basically the same result?

Engineering that don’t exist anymore
It’s interesting
Did you get it running?
Not yet, I’ll be getting back on it soon

Rh5 head?
I’m not sure
