Default LS3 intake valves

Anyone replace their heavy L76 intake valves with the lighter LS3 ones?

Yep, I had that done. Works great. Good for a little extra up top, too.

Will the lighter LS3 valves live long with all the old L76 DoD stuff in place?

Do the valves or heads require any prep work for the swap? Can you reuse the valve seals or did they have to be replaced?

Tea offers them with they're CnC potted heads. I think I paid an extra 180$ bucks for them. I honestly couldn't say if it was worth it or not cause I did the heads, cam and headers all 2gether. I will say the car revs really fast and smooth though ESP for a heavy car
