Read this 41-985 plug.
Its out of my LS2 with an E Force for 5-6 psi boost. It sees boost every time I drive it. All 8 look the same.
Thanks

The tint color on the porcelain electrode shield is just fuel additives.
The rest of the plug looks fine'ish.
As for the plugs you should be running with 6lbs boost on the LS-2, 41-104 plugs gapped at .039.
