Milling 360 heads for a 318

Hey all! I found a set of 76 360 heads. Casting is 3769974 for 250 obo. Cylinder 2 on my 318 has no compression so I'm hoping it's a stuck valve. I'm thinking that while I'm there I should get new heads so I'm thinking of these 360 heads. What would I need to do to make them fit? New pushrods? And what cc would I want the combustion chamber to be for 10:1?
