hi compressions

[Mark Pitts]

Problem comes, trying to work out the shims, so that both stems are =
working together, and not trying to compress two valve springs, by only =
pressing on one stem.

It should be possible to use two valve stems to stop it spinning.  What
about making an oval valve with two stems at the, and machining an
existing four valve head to have two oval valves?  You could use the
existing valve guides.  Has this been tried before?  Could be tricky to
make the valves, with two stems and all, but not impossible.
