No, but Tacos can usually use some picante sauce....

Are there little oiler ports on the pumps?

(O.K., I'll be serious this time)
The motor itself should have an oil port on either end. The bearing assembly
(more importantly) should also be oiled.
BTW, if you ever have a problem with the motor or the bearing assembly,
replace the whole assembly with a cartridge type from B & G or Taco. They
are quieter and there are no couplers to replace (or oiling needed). They
(B&G) usually cost a little over what a bearing assembly alone runs, and a
helluva lot cheaper than a replacement motor....
and less expensive to operate, too.
Which model B&G or Taco cartridge type do you recommend that has a similar
pump curve to a B&G series 100?
I'm having trouble finding a low head/high volume pump like the series 100
for use on a gravity conversion system.

Mark:
IF you are just replacing the boiler and leaving most of the piping
intact..just about any of the cartridge type circulators will perform well
enough to heat the house.
If you are repiping the entire basement..then watch out.
If the system worked gravity it will work with the small circulator....IF all
of the mains are left intact.

It's a converted gravity system with 2.5" mains. They used 1.5" near-boiler
piping and a B&G100 when they did the conversion (I probably would have dropped
it down to 1"). Not planning to repipe the basement - those big pipes make a
nice radiator that keeps the basement comfortable :-)
I'm thinking about switching to constant circulation with outdoor reset and
TRVs on all the radiators. But the 100 has a relatively high amp draw (in
comparison to "modern" water lubricated circs) and I'd like to replace it with
something more efficient since it will be on constantly.
Don't pumps like the Taco 007 need a lot more head than my system will
provide? The pipes are easy enough to measure, and only a few elbows are
hidden in walls, so I should probably compute the actual head. I read
somewhere that most gravity systems run about 3.5ft of head so I've been using
that to look at replacement circs - that may be as bad as sizing A/C by
"rule of thumb" :-)

I am looking at the curve sheet for the TACO 007. It starts out at 10 feet
of head at 0 GPM and goes to about 3 feet of head at 20 GPM.
I don't have the curve sheet for the B&G 100.
The B&G 100 is almost an exact match with the RedBaron 110 (go figure :-)
Starts out at 8 ft of head at 0 gpm goes to 28gpm @3ft head but the curve
extends down below 3 ft to 34gpm @0ft
I'm concerned about the 3ft minimum - says to me it might go out on internal
overload with really low head.
The curve for the 0010 is nice and flat, gives higher flow at low head than
the 007, but also uses twice the power :-(
Maybe what I'll do is try an 007 with a balancing valve on the discharge
side to produce some head.
