What I think is that you can do so much better by sourcing your own parts separately. You will also get more reliable pieces.
For instance, it has been shown that those "black onyx" head gaskets that were all the rave in the past are not holding up. In fact the stock head gaskets are outperforming them.

You may have paid a tad more, but in the end your ahead.
I think the shops will tag you for around 2-4 grand depending on many factors.
Also keep in mind your head must be sent out to a qualified machine shop, checked for flat/straight and magnafluxed for cracking. Should they need to be machined, the limit is 0.07"
If they must exceed that number, you will need new heads (which should also be checked for flat/straight, but you can skip the magnafluxing).
