I thought about adding a lip that went under the the heads. This would help with sealing. However, this would require the heads to be lifted whenever the valley plate is to be removed. I could maybe make 45 degree angles that bolt to the flat plate. Then the plate could be removable still. This would of course bring the price up, but possibly a better product in the sealing department.

One other thought, would anyone possibly want a screw in breather on the plate? This could be an added option. This would allow you to run valve covers with out breathers to make for a cleaner look. If the breather on the valley plate was in the back, you wouldn't really see it even.

Any other options anyone can think of? I am all ears!
