I've never found a difference in brands. Heat range, platinum, electrode style etc. can make big difference though. Using AC R44xls in my 427 now fired by MSD 6AL and pro billet distributor.

I had the OEM specified AC Delcos and recently switched to standard type Bosch Platinums equivalents. Both plugs run great with the CFI engine.
