You should buy it for sure. Those DG heads are nice looking, otherwise no improvement over stock. I've seen them go for $500 if in good shape. I've got one thats all tweaked out, and it is so much fun, it's absurd. If you buy it, be ready for someone to come up to you every time you fill it up with gas, who had one back in the day, and is dying to hear you start it up, so he can feel all nostalgic. A piped RD will make you an expert in jetting carbs. Have fun, and please put up pictures if you get it. And by the way, there's a 2 stroke sub-forum in Old's Cool. Check it out.
