sparks plugs for 350

i got a '96 sonoma. got a 350 motor out of a late 80's van. it's bored out, got a bigger cam, edelbrock 650 carb, nothing too crazy. but it is a little more beefed up. i have standard autolite spark plugs in it and i'm gonna change them out. i bought some autolite platinum plugs that i was about to put in. but i was told i should probably run a "hotter" plug. will these platinums be good or should i be looking for something else? i just want it to run better. changing the plug wires seem to help but these plugs are a couple years old and haven't really seen much road time. just a TON of starting/stopping to get the motor done. thanks for the help.

alot of people run autolite 26 sparkplus in the redneck area i work in, and theres firebirds and elcamino's with mullet drivers everywhere!

ya i heard the platinums i bought should be good. i'm gonna throw those in tonight. and hook up my new switchbox.
