make sure they size it to whatever piston you buy for it. That 's important. Also make sure they deburr the ports, CV-tech did a really good job of this and it's important so you don't snag a ring. I would recommend a wiseco although your bike will have to be warmed up before you go belting on it. Not a bad practice no matter what you put in.
Also the cylinder should have no pin holes in the plating when you get it back. If they say it's for holding oil call bs on that one and have them re-do it.
Good Luck

I would leave that to an experienced tuner. Shaving a head can involve very critical work. Just send it to Ron Black for his head mod. For the same money, you may have a hard time finding someone to simply shave the head.

You don't really shave the head on a 2-cycle like you may do a little on a 4-stroke. It's all in the squish band area of the head, and is profiled in on a lathe. RB has the pump gas to the max profile all figured out.

That's pretty normal. Don't sweat it too much. Send the cylinder off. I bet you have a crack in it just under the exhaust port running down. Again no biggie. I also bet the center powervalve is fine and so is the metal shaft with the gears cut into it. I would bet that your 2 side valves are pooched but the idler on the right side is ok. Did you support the vertical shaft actuator when you loosened the left hand thread nut on top of it? Hope so. I've heard that Honda parts has the cheapest price on powervalves for the e-series. So look there.
If you have any of the parts I listed as probably ok that arn't then let me know as I have spares. I also have a spare junk cylinder for replating but you don't need 2 of those.
Hey, at least you know what you got eh?
