Although the Service Bulletin identifying Allstate-Specific Parts lists only Auto-Lite equipped engines, some Allstates were probably built with Delco-Remy electronics. The engines should have the same brand generator, starter, voltage regulator and distributor; spark plugs and batteries were the only Allstate-branded electrical parts on the cars.
The part numbers for the engines on the Allstate-specific list (6-digit part numbers starting with "4" rather than "2") also reflect the Allstate-specific cylinder head (no "Kaiser Supersonic" on it) as part of those motors & the blue rather than green paint jobs.
