OK I've pretty much decided on the single groove valves...now anyone have
any real strong feelings one way or the other on the merits of swirl
polished valves for a truck engine? The difference is significant, about $3
a valve...TIA

I'm also curious about this subject. I've asked the question of standard
steel vrs SS valves and plain SS vrs swirl polished severe duty SS on
several lists and received limited responses. They go like this:

1. Undercut, swirl polished severe duty SS are great for engines runing
at sustained high rpms. NASCAR and other big boys have used titanium for
years, so is SS a 'middle of the road' option? Are regular SS any better
than OEM steel valves?

2. I have yet to hear of anyone burning or dropping an OEM steel valve
when the assembly is put together correctly with the right components
and operated with the correct fuel/air mixture.

3. None of the factory muscle cars ever used SS valves and they were
produced primarily for NASCAR, drag and track events.

That's what I've heard. Nothing scientific but lots of looking for that
extra edge in competition. Not being into off-shore racing or other
'severe duty' applications, I still don't know the advantage of SS over
OEM steel.
