Hello team. This is my first post on the forum. I finally joined the team a week ago after viewing the site for a couple of years. My question is a relatively simple one. Is there anyone out there that is currently running roller rockers on a small block chevy with the factory aluminum finned valve covers that were installed on Z28's and later model vette's? I want the original look under the hood of my 69, but don't want to give up my rollers. If this is possible ,were any modifications necessary?
