I saw a cowling split along the top so each side lifted up. It was by Gary Newsted and unfortunately he no longer has his web site up. Gary did a super job on his RV-9 and his website was top notch. You might do a search and someone may have it archived.
The following link has a photo of Gary's plane but I don't think you can see the cowling design.
