Early 318/360 magnums had the provisions for oiling through the block also fyi. More curious how low the compression will be with open chamber heads. Stock Magnum is supposed to be around 9 to 1 with stock closed chambers.
Oh interesting on the oiling, thanks.Yup I really want to know what heads it’s got. I’m assuming it’s got some terrible smog era heads, so that why I figured the X head would be better.
