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.

No you can't just randomly change parts.
The is no such thing as a 50cc 2-stroke, they are 48cc.
There is no such thing and an 80cc, they are 66cc.

An expansion chamber on a 48cc makes it damn near as strong as a 66.
An expansion chamber on a 66 gives you even more.
