<VV> Fwd: Fw: bronze valve guides

[Dennis Pleau]

The reason is to get some lubrication between the valve stem and guide.

Intake valve stem seals are pretty much required 
when the valve stems are vertical, but with horizontal stems, like on 
the Corvair and others, the seals are generally considered optional by 
most of the folks that I know.

William Wynne of FlyCorvair.com fame told me NOT to install intake valve
seals when I was looking into building a flight Corvair engine. I wish now
that I had asked him why.
