Which TR55 for blown 5.3L?

NGK has the following - which do I need for my Radixed 5.3L?

TR55
TR55VX
TR55-1
TR55-1GP
TR55-1IX
TR55-1VX
TR55GP
TR55IX

Or do I perhaps need the TR6?

I'd use the TR6 with the gap it comes with out of the box.

Talked with NGK and they said to get the TR6IX plugs and regap them to .40 to .45. What do you guys think?

You do not need the iridium plugs. Get the basic tr6 and leave them at the .038 gap they come with.
