    Im wanting to get a slant head for my 49cc ht. The only one I can find is a round head, will this work as mine has a square head?

    The only difference between the heads is fin size. Compression is within a few tenths.

    It's when you get into exotic heads you start having problems. There are many moped heads that fit the Chinese motors. I have a Puch Hi Compression head. It MIGHT be too much compression but I'm going to machine out the combustion chamber a bit.

    At the bottom of the page is the head I got. You do have to run a colder plug with it. A B9HS is hard to find but works the best I understand.
