    66 cc engine heads left to right. Stock straight plug head = 10.1cc's. Stock slant plug head = 6cc's. Pancake performance head = 7.9cc's. Round finned performance head = 8cc's. Flat fined performance head = 8cc's. While these performance heads are far better made than a stock head, they won't increase compression unless you are replacing a straight plug head. I am not sure how the squish band effects pre ignition if at all. If it has no effect than there should be no worry of early wrist pin or chrome bore lining failures.

    pancake and flat finned head from kings. The flat finned head (far right) is off a GT 80 engine from kings, but they sell them separately. The round finned head was from mzmiamiparts out of Florida.

    this is fortunate for me because I own a Suzuki AX100 and they sell parts for it. No parts for it are available down here and the main source for its parts in England has a problem using my debit card. So thanks.
    It also brings back memories of the MZ I used to own when I lived in Dallas. It was crummy but free so I rode it till it self destructed the crank.
