Delco spark plugs
I am looking into replacing the plugs in my LT1....and also the 4.3 in my van. From what i hear its always best to go with factory plugs...but i have heard that the platinum tip on the Delcos comes off 
Is this true and if so should i use different plugs.

When I pulled my old platinum plugs, all of the pucks were missing leaving the gaps in the .080 range. I have since opted for the copper conductor NGK TR-55s so I know longer have to deal the platinum pucks issue. They work just as well as the factory spec plugs in my opinion.

LOL I wouldn't touch the Boschs with a 10 foot poll 
Looks like im gonna be picking between the Delcos and NGKs. I don't intend to use any N20....would the pucks still fall off the Delcos even without N20?

Using nitrous won't cause the pucks to fall off on the platinum plugs. Its not even advised to use platinum plugs and spray anyhow. And yes, if you don't want to change plugs as frequently, go with the iridium, they will cost a little more though.
