Looking for a little help

Looking for the best matching paint to use to repaint the frame and motor with. I was going to powder coat but time and money is a little tight right now. The frame has very little rust and is in great shape so thats why I was just going to paint it for now.
I am also looking for a really good sleeve, piston and gaskets kit to redo the jug. Is there anyone that has a all in one kit to do this.I'm also looking to not max out the jug but looking to go big just not full out. What the max cc you can punch these out too?
Im also looking for info on porting the jug. I have done a lot of porting on engines but not one of these. Is there a youtube vid or pic's on how to clean one up?
Thanks Charles
