Yesterday I gathered the TrickFlow center bolt adapters and attempted to install them and bolt on my new valve covers. What I discovered was that the adapters will not work if you are using anything but narrow rockers. My Comp rollers are to wide to allow the adapter to drop between them. Well shoot.
So, I spent the afternoon polishing the original center bolt covers and licking my wounds. If anyone is interested in converting from center bolt to perimeter bolt valve covers and are running standard rockers or just need some custom "GMC" valve covers, drop me a note and we'll see if we can work something out.
