Thanks for the replies ...
I found the NGK at summits store .. but it says it is only for 2005/2006 LS engines.. mine is a 2007 Corvette engine .. will these fit also ?
Any other brand you can recomend or just the NGK ?

Assuming your running 243 or 799 heads the NGK TR5 is the correct original heat range plug for your engine. If the engine is lightly modified, this heat range is fine. Personally, I prefer Iridium plugs so I would use either a Denso IT16 or NGK TR55IX.

how do you define slightly ? the cam is a race cam and agressive and the heads are also fully portet ... should make nice HP.

I would run either the NGK TR55IX or Denso IT16 for this application. I'm running 11.31 SCR, Dart 225's, Crane 222/228 cam, FAST 90, Dynatech longtubes, and Crane rockers with NGK 6 heat range plugs (BKR6EIX-11, DO NOT use this part number for your heads, they are a gasket seat for Dart heads).
