where is the occurring and why assuming a likelihood ?


When Dwayne P. freshened up the heads, he mentioned seeing more indications of reversion in the intake ports than expected. The cam's worked well on the dyno and the track, but might have a bit more overlap than "ideal" for a full exhaust system and street-driven car. No plans at this point to change the cam (again), so I was curious if the phasing might have any impact on it.
