For sure electronic ignition. But retain the Lucas dissy. I would not waste any money on a Pertronix unit.
Go with a bigger Carb...Im assuming the engine still has the Weber down draught...
If the head is off, do the unleaded conversion. If you dont have to take it off, dont sweat it. Just run regular pump gas. The leaded heads will last for quite sometime before the ill effects of the unleaded fuel will manifest.
Or the you could do what I did, and just swap it out for a Cosworth BDR...LOL
