Got the part number off the exhaust valve. 021109612A
After an exhaustive (get it?) search on the inter web I can only find that it was used on type 4’s from 69-74. No mention of their sodium make up. All this to make sure I get them adjusted properly. |

The sodium-filled 1.8 exhaust valves were not standard. I think they may have been an option, but they weren't standard issue. Just the 2.0 exhaust valves were sodium-filled as a matter of course.
Current thought is that the sodium isn't needed with modern materials. --DD |

I use the TDC mark on the flywheel to set my valves.
There is the original at 0 deg TDC, and I put a second mark (with paint) at 180 deg. That way I can see the mark(s) from under the car and just turn one wheel to spin the engine. |

This animated gif helped me understand the Krusty method. There's a way (I can explain if need be) to look at the gif "frame by frame" to see what valves are closed when.

No reason to use sodium valves today. None.
There are only 2 Type 4 head builders that I would allow.... Hoffman Automotive https://newsite.hamheads.com/ or Headflow Masters http://headflowmasters.com/ |

Please don't use 40 year old sodium filled exhaust valves, corrosion never sleeps and can lead to disaster !!
