Im sure reversion starts on the exhausr side. and Solved with the exhaust Collector length.

The word SOLVED being used. Surely the Cam profile (overlap) begins the need for a sufficient exhaust Collect length.

Seems to me, the only way to push fuel/air back up the carb venturis is with Exhaust-originated reversion.
