I'm running the Comp Cams Pro Magnums on my Edelbrock Alum heads. Just need to know which valve covers will fit without modification.
Big thanks for any and all help!

Silver call your local speed shop they sell spacers that go between head and V/C

I have Crane Roller Rockers and I use Moroso Tall BB Valve covers. They fit fine.

I also have crene roller rockers. I use stock valve covers w/o drippers and the extra thick valve cover gaskets from mr.gasket.

I use the Canfields with stock covers without drippers also. I have the same rockers you have. I also use the 5/16" Gasket. My cam has .630 lift and I have a good bit of room.
