Links to porting threads in one place. Please no banter there's plenty of places for that.
Feel free to post your favorite thread link. Here are some to get started.

http://opeforum.com/threads/part-two-the-intake-port.7290/

http://opeforum.com/threads/part-three-the-transfer-ports.7306/

http://opeforum.com/threads/part-four-compression.7318/

http://opeforum.com/threads/part-six-the-exhaust-system.7372/

http://opeforum.com/threads/part-seven-carburation.7395/

Edit: either post a link or post will be deleted. It's the only way this thing is going to be functional if it's only a page or so long with just links as the originator intended. Thanks for your cooperation.

I'm working on an Echo 590 hybrid and I was thinking that if I take the lowers on the 440 cylinder down to the flange it would give it a little bit more bottom end capacity, am I thinking about it wrong? I've already done it to this cylinder so I'm just asking for future builds.

@Mastermind Can you move this to transfer thread, I posted it in the wrong place?

Remember when looking at such things that is part of the base and its strength.

I didn't remove much material, just tapered it to the base.
