    Well, It's come to that time where I'm getting bored of the ported sport(Not my first time doing this ;) ), It says that the mkII will be up too 17bhp, With a bit of port work It could easily hit 20bhp, What is the best way to go about the bridge in the exhaust port, It's there for a obvious reason, Should I just match the stub all the way too the bridge or all the way down, (Will be ran with a c16).
