Less HC, I think.

I try to keep the valves locked into spec.  I have noticed that a 
change of just .001" seems to make a big difference, at least in how 
smoothly it idles.

Essentially none.  The PCV valve is in place.  Carbs are HS4 SU's 
with individual K&N air cleaners.  That's what it's had since I 
bought it.

As for my emission testing equipment, that's my nose.  And the state 
of my clothes when I get to where I'm going after idling at enough 
stoplights.  All very hi-tech equipment, you know.
