Well, I just called the local dealer.
Parts breakdown: (dealer costs)

exhaust valve: $42.84
intake valve: $29.06
valve spring: $13.20
retainer: $5.10
head gasket: $88.58 (just in case)
exhaust gasket: $15.18 (just in case)

I need to find a couple of these parts cheaper like the head gasket. Where, who, how much?
