[TR] Valve Seals

[Roger Elliott]

Hi Bob,

The Spitfire engines did not come with seals.  But many people much more 
expert than I,  recommend using putting seals on the valve stems when 
rebuilding.  I am pretty sure it was one of the recommendations in Kas 
Kastner's books though I don't have mine handy to confirm that.

I had them installed on my 1500 engine when I had the head done last 
fall.  So far I can't really comment on the benefit.  I would think it 
would help reduce oil consumption.

However as you said they were built without them originally and 
performed fine.
