I heard no, that's why I never changed. I also talked to a few people about pinning, or staking the seats, some said it would fix, others said no. I have a guy locally that build some awesome motors for all types of motor sports. He said what my head was doing, their wasn't a way to stop it, other than doing all the seats and installing larger seats. To where they had a tighter fit in the head. Even them he said no promises.
