Budget 318 build

Was that an allpar article? I found it and read it that is some good info thanks!! So it said evey .005 milled off the head is 1cc so i could mill .50 and take of 10cc with a 73cc head that would put me back to where i am now with stock 318 heads could i run that setup with factory rockers or would i have to switch to adjustable like it says in the article? Cause lets face it thats more $$$$ lol does anyone know how much the average head milling costs?
318 heads work well on 318's, especially with a little home porting. 360 heads work better IF cut .040. You can use the 318 push rods/rockers. they are the same as 360's anyways.
Key to head performance starts with valves that seal and good valve guides. IF the valves leak and you have sloppy valve guides, you performance and gas mileage just took it right in the gut.
