"... installing a a points style distributor..." The conversion kit is for a points dizzy. Using a points dizzy and converting it to electronic is redundant. Just obtain a DS2 single vacuum advance dizzy and ignition box (with a blue grommet) '83 or older or use a 4-pin GM HEI module (I suspect the conversion kit is an HEI based item) and you are good to go.

'86 is too new for me to have any experience (Duraspark THREE?)
but here's a post of a guy going from DSIII to HEI:

ok- so just to recap the options for the OP:
1. points conversion
buy points dizzy, electronic conversion module
2. DSII conversion
buy DSII dizzy, DSII module
3. DSII/HEI conversion
buy DSII dizzy, HEI module
#1 is the most expensive, and you can't easily get replacement parts.
#2 and #3 cost about the same.
all 3 will handle a full 12v if you source the right coil.
between #2 and #3, the HEI probably means less wiring...but #2 has the ignition retard feature.

Am i correct?
use full 12V with a 3 ohm coil
use 1.1-1.5 ohm ballast resistor with a 1.5 ohm coil
Thanks to all...jack

just buy a coil that can handle 12v.
for instance- the MSD page says this about their Blaster coil, which is 0.7ohms:
Most late model vehicles with electronic ignitions do not require a ballast resistor, check your ignition and manufacturers specifications to determine if a ballast is required in your application.
You'll be a long way from stock, so just figure out what your components can handle.
So- because (unlike points) the Pertronix/HEI/Duraspark module can all handle 12v- there'd be no need for a ballast resistor in this setting.
MSD Blaster coil, stock TFI coil, Accel coil...all would be good choices. Basically, anything other than a stock points-style coil.
