I have more to update on my valve cover.

It is now made with a variety of finishes.

As cast (exterior is not blasted or sanded)
Blasted
Polished
Powder Coated

Other choices
Polished tips

Another variation is a NON Finned or smooth .

Here is a video that shows fitment with roller rockers and comparison of Clifford and Offenhauser valve covers.
