Sorry, but no. The head stud spacing is different. And no, it can't just be drilled out. It's a completely different engine. You can get just the engine, and all the other stuff will work. Carb, exhaust, cdi, etc... it's all the same.

Here are some videos to help you ID your china girl motor. There are no universal terms for these motors and people call them by different names. This will kinda help explain the differences.
