That is strange. I would think not possible that they'd design their highest flowing heads, which folks would put high lift cams in and then place the spark plug in the path of the exhaust valve travel?

It could be detonation.

I'd make sure you have fresh gas, plug gaps @ .035". Whats your Base and full advance set at?
