360 heads on a 318, I know it has been beat to death...

Clean them up and put on the new valve springs. After that, the amount of actual cc's the head has would help me determin what I would need to mill off to get where I wanted to be.
It's been awhile since I had heads milled, but I payed $35 a head for a light cut. (Though my buddy said he'd do .060 for me)
Springs are easy. I used to do them for a nice sandwhich for lunch. But that was a long time ago. LOL. I guess I'd charge $60 for the springs, head milling around here at a good shop is about $100. Pro shops charge more.
