Ahh, the thread you speak of is here break>

Translators play hell with the words but you get the main meaning. The magic numbers are 140 degrees intake, 150-155 exhaust, 110 transfers. In practice those are hard to make on the intake and transfers. You have to cut the intake down pretty far and cut the piston up pretty far. The exhaust, make it an oval, about 23-24mm wide and 150 degrees up. These forums are not the same as ours, the expect you to know a lot more and tune a lot further than most of the threads here.

Another great thread is this break> It's for the AV10 but the information applies mostly. Notice the level of detail in the breakdowns. He gives you fuel consumption rates for christ sakes.
