I'm looking to get edelbrock heads to feed my 360 kenne bell sc. I remember my installer couldn't even get the mopar perf. valve covers on a year or two ago. Now fastman says I'll need bigger valve covers. Is this doable? I'm getting an M1. Maybe it'll help?

Well the only reason you need larger valve covers is because roller rockers wont fit under the stock ones. Well they can, but you need to hit the oil baffles in a bit. Since you already have Roller rockers under your stock covers you really don't need them unless you want them for looks. Why wont the perf. valve covers fit? Does the s/c get in the way?
