Notice how they seem slightly higher in the middle, front to back, than the flat M/T style. Even Cal Custom BBCs are flat from front to back (radiator to firewall.)

At least on the small blocks, the curved script edelbrocks were the first design. The straight script came along a few years later (mid 70s, I think). From what I've been told the big block covers are the same but I have not confirmed that.

There ya go!

New versions of the Edelbrock 4185 Classic Series Aluminum Valve Covers for 65-Later BB Chevy V8 are 95% correct referenced to the original 67 Edelbrock Chevrolet Valve Covers; V8 396-427 '65-67'; Part #4180. The original version have the oil filler cap in the opposite location.
