What are the best and most reliable new spark plug out there for a 1987 350 TBI engine ?

If you want the very best go to AutoZone and get a set of E3 plugs. With E3 plugs, it's critical that they be gapped at .034" - .036". No more and no less. Then you'll want to have a set of indexing washers handy, I prefer the Moroso brand, and install one thin washer on each plug. Finally, toss them all in the trash and go get yourself some AC Delcos.
Autolites.
He's not working on a Pinto.
So, AC delco autolites are the best option. What gap do I set them to ?
So I hate to revive older threads but has anyone seen Bosch in these engines? I've been chasing drivability issues and I go pull a plug to get an idea of the IGN system and how the engine is running and there's bosch plugs in the truck!
The plug is a orangish white and not overly worn but I've never seen bosch anything work on a domestic vehicle.
