SO you port every head the same because they are all the same? Its funny when I read stuff from guys that do this for a living say that over time they figure out how to get more flow for less work out of the same casting........

Let’s just say you can grind like crazy in areas that you think a head needs grinding and never pick up 5 cfm.
