Optima 6V redtop (also got a smart charger designed specifically for glass mat batteries from the on-line Optima supplier). Leave the charger connected during times when the car is not used and you needn't worry so much about regulator under-adjustment. Oversized cables, clean grounds, starter rebuilt with high-torque windings, no more starting troubles.

P. S. I tried the 6V Pertronix, but my O.D. solenoid pull-in coil draws so much juice, that when the bright headlights are on the engine misfires at higher revs, so I went back to points. Converted my Loadomatic to dual points and bought a large grab-bag of old NOS condensers and tossed all that were out of spec., so no more ignition issues.
