Sorry I got that wrong, I thoght you were drilling holes in plywood soffets which would hide all that, that 2x4 you have drilled is not usaully there when the soffet is covered.Here's a pic of what I have. The holes are the venting that I have been adding.
That Smartvent product looks like it could be a great solution. My only concern would be it working (or not) in combination with all the holes I've drilled out in the eaves already
[EDIT] Never mind, I just found this on their site.
"Can SmartVent be installed even if there are perforated soffits already installed?
Yes. SmartVent can still be installed even with perforated soffits because you can really never have too much intake ventilation. The ridge vent is going to be your controlling factor so it will still suck air from both the SmartVent and the perforated soffits."
