340 Lifter Clacking.... Reasonable Price?

Well, if it's just "dropping one lifter in" then from me it would be about 2hrs work plus the price of gaskets for the intake and valve cover and one lifter. At a shop here (CT), that's about $200 after tax.$75/hr labor is average. Some places less, some places more..I've heard Firestone charges like $95/hr. That's frightening after seeing what they can do for damage in an hour.
