Which valve covers
...to clear full roller rockers and that will fit under the wiper motor and large diaghpram power booster?
Seems simple but I'm not finding much unfortunately. I have a set of old Holley - M/T finned covers and they are just a bit too short and end up riding on top of the poly locks. A standard 3.5" valve cover should clear the wiper motor theoretically and provide room for the rockers, but won't clear the power booster. Do you guys have any recommendations?

I run factory 69-70 style covers with 1.65 H&S rollers with a 400 lift cam and the 5/16 after market gaskets.No issue with the large booster in 69 birds or 69 GTOs.Tom

Do you know the inside height on those valve covers?

I am using the Tomahawk finned covers with thick gasket. Tried the chrome tall covers, but it hit the brake booster. The Tomahawk slopes down to the front and back, and clears my roller rockers..
