when a manufacture makes a gasket the very last thing they are considering is if the size of the hole around the port is going to optimize the head. Where does this craziness come from? 
Making the port gigantic at the entrance is not a way to gain power. Actually, it's a great place to lose power by doing so. Shaping the port like this will bell mouth the port and make it lazy.
 Now, this is not a blanket situation. There are some heads that porting to the gasket is not such an issue, and can be a gain IF the port is optimized with the size of the entrance.
 But some others (like this subaru) are just ludicrous to think this shit works...
