Machining cost

here is my question. I am starting to think about the winter motor project. I simply cant figure what my options would cost. Every shop that i have stopped in to talk to, have told me that they would need to see what they are working with before any cost talk can go on. I am just trying to figure out what direction to go. I have a 318, trying to figure out if i should do heads cam carb intake, or have it bored and decked. What was your maching cost, and what was done? Thanks!
