Even though I'm not Matt...

Yes and no, in that order!

It's a bit more involved than just opening out the boost port though, you need to get the shape of the whole length of the port correct to get the most effective gain.

Take the exhaust port out to the shape of the gasket and you will bugger the barrel completely.

I would say that if you really want to have a go at the barrels yourself, then for the time being, stick to "optimising" them, i.e. square (even) all the ports up so there are no uneven edges, as per the guidelines in the tuning section.

I think I can pretty confidently say that neither Matt or anyone else is going to tell you how to get a lot of power out of the porting as it's cost him hundreds of hours and probably thousands of pounds in development time finding out for himself! It really is a "try it and see what happens" affair, although I couldn't stand by and blatently watch you scrap a set of barrels by screwing up the exhaust port exits!
