Performance upgrades for the CSC SG250?

I'm considering buying the CSC SG250 next year, and I'm wondering what performance mods are available for it. It's a very low compression motor to pass CARB... and I'm sure there are some more ponies to unlock. Before I go chasing performance, are there any kits or a list of what has worked for this motor before?

It's a 229cc OHV (pushrod) mill. I was thinking to start with a port/polish and deck the head, and see where that gets me, before seeing if there's a larger jug and piston that can be bolted on. Not sure if there's a cat in the exhaust, but obviously a new exhaust and intake will happen as well. Just curious what can be done with this motor.
