Let us assume for the moment there really were an exact low cost copy
of the Lycoming exhaust valve out there. What effect would that have
on Lycoming assuming all the experimentals guys found out about it
through the internet and starting buying them to overhaul their engines?

I think Lycoming's cost would go up and they would raise the prices even higher
than they are now and more people would consider experimental airplanes 
for their needs.

If I owned a Lycoming and an experimental airplane I would be spending 
my time in truck part dealers looking for something that fit.

$290 per exhaust valve is highway robbery by anybody's criteria.
That is almost as bad as my Cessna 182 $100 dipstick.
