Dave,
Beautiful website. Enjoyed the pictures of your 2.1 engine rebuild.

You wrote on your website:
"P.S. The factory used cheap non-sodium filled exhaust valves
on my old factory rebuild, the OE are supposed to be sodium filled."

A question: Years back I bought a spare set of 2.1 liter
cylinder heads for my vanagon. They are the ones that were
still made in Germany.
How can I tell if the exhaust valves in those heads
are sodium filled or not?
Also where did you find those 2 other sodium filled valves?
I guess they are pretty hard to come by.

I agree with you on the dealer rebuilts. Been through that myself
with my former '81 aircooled westy.
