I agree, Jim.. good price, though still expensive when doing it yourself is a MUCH better gain, and gets the gaskets replaced while you are at it (avoiding unmetered air, CEL's being on, and codes being thrown, and performance being hurt, as well as gas mileage.. at 110k, they may very well need to be replaced!
I would charge about $60 plus gaskets, to do it by hand, FWIW.
