		Steve, I have ben running a set on one of my stroker 427's (452 CI). The Erson's are the best engineered rocker setup on the market, they are a no brainer bolt on for a 390 or 428/ 428 CJ. If you are running Edelbrock aluminum heads Erson offers a spacer kit to make the tips align properly with the valves. I am running the stock chrome "Power by Ford" valve covers on my 427 with the baffles in place. No problems of any kind, stock pushrods were perfect. I am running fairly stout Comp Cams valve springs and stock length Crane pushrods. My cam is 240 degrees at .050 and .550" lift.
