10V head mod qustion

[Konstantin Bogach]

I searched archives on subject of bigger valves but I could not find
much on turbo engines. There is discussion on NA engines but not much on
turbo.  So, what is general consensus on installing bigger intake or
exhaust valves?  Is it worthy to do that on these cars ?
Can I use not sodium filled valves in this cars?  What is a downside?

I have neither experience nor theoretical knowledge in
technology/materials used in building heads.  I use Napoleon's tactic -
engage first then see what you can do.  I engaged already by planning
taking head off my car tomorrow.  Now... I will appreciate if someone
point me to ABC of head rebuilding (if such write-up exists in first
place).  I also need a good source for rebuld kit for K-26.  I called
ont place - $125. Sounds like big $$$.

Thank you.

Konstantin Bogach.
