318 low budget heads change

Ok,

so I called a shop in my area, and they ask 200$ for milling both head (including intake face), have the heads magnaflux and check them for leaks. Sounds fair ...

Can't seem to find the info, but I read somewhere that each 0.01" milled remove ?cc in the combustion chamber of the head. Anyone knows on a 360 head?

Also, if I have the head mills by 0.05", the intake side need to be milled also. I have found this chart http://www.mymopar.com/downloads/intake_head_milling_chart.jpg ... anyone can confirm these numbers?

Based on my shop manual, I have an amazing 8.4:1 compression from the factory ... :banghead: better not lower that number
