Will boxing-in roof eaves exacerbate mold growth?

Im re-stuccoing my older craftsman style house in Los Angeles. There is a lot of black mold under the roof eaves, perhaps its because of the oil based paint that was used years ago. The stucco guy wants to pressure wash off the mold (with 10% bleach), and then box in the eaves (to make a smooth surface), and then stucco over them.
Im worried that the remaining spores will just grow inside the boxed-in eaves, and I wont be able to see it, or get at it again with a pressure washer.
Also, I see some boxed-in eaves with vents. Does this help prevent mold by drying out the inside, or exacerbate the problem by providing an opening for air and moisture?
Is it best to sand blast off the oil-based paint, re-prime the wood, and use a latex acrylic paint, and leave the eaves exposed?
Thanks for any insights.

photos of eaves

Hi again.
As a picture is worth a thousand words, I attach some photos of my eaves.
There is no attic above them--so would it be OK to box them in without venting? Would covering them in stucco prevent moisture and air from getting inside boxed-in eaves, such that there would not be mold growth inside? Or should I paint them (e.g., with Messmer's acrylic anti-mold exterior paint), and leave them exposed for periodic cleaning?
Thank you for any advice.

They have mildicide that you can add to paint. You might want to bleach it good and then try some out to see of it works in your situation. A lot of times they water the paint down so much that it doesn't seal the wood adequately. I've noticed mildew and mold grow on those type of jobs more easily.
