I believe those 50cc heads are on a 21 degree valve angle (they've been angle milled 2 degrees), if that is the case it may be a headache to get the intake and exhaust to work right.

To be honest a simpler way to see a power gain would be changing to a better intake, milling the heads you have and maybe getting them ported, and getting a different cam.

The total cost will be the same but it'll be an easier approach with less headache.

Adding a supercharger or a shot of nitrous would also work- if you're willing to consider that.
