Cylinder Heads 101

I think the cost of the builds would be good only to a point of what you have to start with and what it needs. What parts you have or not. The area of the country you live in on machinest costs as well as the place you have your work done can vary much.
I believe a general cost figure would do better. Trust me, I know theres a screw ball here or two thats gonna complain when the get there bill and only point to this site.
I myself plan on doing some simple mods on the 318 and run to the track a couple of times.
