Yes, you will need a valve spring kit. I am also going to move this thread to the 4-stroke section.

Thanks

That's right , you will also need to change the piston or your valves will smack the flat stock piston.

I would be afraid to. The piston is a cast and will be pretty thin, to much heat could break or blow through it. You could get a 11.5 for $260 and be safe and still run pump gas.
