The dealer here told me a little over $300 to do the VC gaskets. I didn't ask how much it would have been for the spark plugs though. My VC were leaking when I first went to synthetic, but I switched back to dino, then to Valvoline Maxlife and it isn't leaking anymore.
I still do plan on changing the driver's side VC gasket, but I'm not going to do that until I'm ready to change the plugs. You have to break down the VC to get to the plugs anyway.
