LT1 switching to LS2 COP setup. need to change sparkplugs?

I have switched my LT1 over to Coil on Plug using LS2 coils.
I'm curious if I should be changing the plug to a different type? Hotter, colder etc?

Thanks

Mmmmm……hardly an expert on this, but I think you just get better ignition. Your plug needs should not change.
Personally, I like Denso "Irridium Power" plugs. Get a noticeable improvement using them.
