I would do (4) things different:
1) I would go with an aluminum head. The weight savings alone is worth it, and the alum dissapates the heat better, helping combat detonation.
2) I would go with 1.6 rockers and a cam that will work well with them, a proven custom cam from Bennett.
3) 24 lb/hr injectors. I ran a similiar set up with 19 lb injectors and had to run excessive fuel pressure to make good HP. The injectors could not with stand the abuse and a fuel wash problem occurred, which caused damage to crank bearings, pistons, rings and a couple of rods. When I rebuilt it I went with the 24 lb injectors and ran better ET's with less fuel pressure.
4) 70mm Pro-M mass air meter. As long as you are changing injectors it would be a good time to upgrade the mass air which would be calibrated for the 24 lb injectors.
Good luck and let us know what you decide...
