Default Angle Milling cylinder heads and radial P/V clearance

OK, I get the jist of angle milling but I was wondering if someone could go into more detail.....I'm assuming if my heads were say 20 degree heads you'd want to angle mill them into maybe 19 degree or 18 degree heads and not the other way around. I'm considering doing this to increase my compression without shrinking my vertical P/V clearance....

Does angle milling disrupt the airflow at all? It just seems that the chambers would be at an awkward angle sitting on the engine. What is the minimum radial p/v clearance you want?

Angle mill the heads and than angle mill the face of the intake side to make it match back up to your intake. This combo works! Much smaller combustion chamber and less milling.
