440 Roller Cam suggestions

I'm slowly gathering parts for my stock-ish RB440 six pack build, and I'd like to run a stock-ish hydraulic roller cam. I want a smooth idle, and I figure stock 440+6 power is plenty for an A-body. What kind of roller cam specs will compare to the OEM .450/.458 cam? I don't mind if it's a step or maybe two steps over a stock cam, but I don't want or need a lumpy idle. Car is street-driven, and I'll use some variety of A-518 or 727 behind it. I am interested in ROLLER CAMS only.
