I had the Holley Tall Valve covers on the engine and in the car, but I ran into trouble when it came time to install the coils. The stock coil bracket was no longer useable and the hole pattern from the pedestals on the new valve covers were different than my stock ones.
The whole reason for buying the Holley Tall Valve covers was because my Comp Cams 1.72 roller rockers were too tall for the stock valve covers. Since I had to take the valve covers off, it was a good time to paint them. I bought the cheapest option from Holley and I never really liked the way they looked.
After 3 coats of Chevy Orange and 3 coats of clear, I was ready to start on some custom brackets to get the coils to mount on the valve covers. Apparently MSD makes some coils with the mounting holes 72 mm apart, but I had already dropped serious money in some genuine AC Delco replacements which had the mounting holes to fit the stock coil bracket.
So I had to drill larger holes in the mounting holes of the coils and I made my brackets out of a strip of $4 aluminum that I bought at Lowes, and slapped them on. I think they look pretty good, all things considered.
