greetings:
  perhaps, then, you could explain why going to stainless steel valves
is an 'upgrade'?  in light of it's poor heat transfer, what might be a
reasonable material for an exhaust valve (due to excessive heat)?  yea
i know titanium is the 'best' due to weight & fatigue factors, but how
well does it conduct heat?  (anna one-a, anna two-a...<cue bubbles> :)
