For an unmodified street engine AC-Delco iridium spark plugs seem to have the correct reach and heat range for all GM engines.
There are a lot of trick spark plugs out there. Bosch with their multi-ground tips, E3 with the crazy shaped ground electrode, Denco, NGK, Autolite, -- forget Champion etc.
I ran across some other plug on the net the other day that had what looked like an added coil winding inside the porcelain. Supposedly they provide a total of 80,000 volts the the spark plug gap.
Autolite's do however work well in modified Chevy small block.
