no it won't as where the rocker cover fits to the 1/2 moon at the front and rear of the head late ed onwards are rounded and ea- early ed are not so just wait for the head swap. look at the front of both heads together and it will be obvious.

I had an EF rocker cover on my 3.9L with the original rocker gear, and now an AU rocker cover on my EF engine. The only problems are fitting the spark plug leads and throttle cable on top of the rocker covers.
