Valve springs for Eddy heads

Has anyone changed the valve springs on eddy heads?The springs I need for the cam I am running are dual springs and the inner spring fits over the seal but there is a little interference between the spring and the seal. I think it is okay but am not sure. The springs I need to use are comp 987's. Anyone had any problems with these springs on eddy heads? The eddy retainers looked like they would work with dual springs. Niether edelbrock or comp would give me a straight answer.
