Can i just check, by 'all the timing gear' is it just the rocker gear that needs swapping from the early head into the au to fit the early cam, not the timing sprockets as well ?

Also i noticed on the JMM article it says the ef/el had large ports and the au relativly small ports, so is putting an ef head onto an au a benifit ? Not sure how much compression would be effected.
