Is this LA360 XE268 cam kit deal good for my combo?

I found a Great deal on CL for a brand new Comp XE268 cam kit (cam,lifters,springs,keepers,seals,retainers,timing set).
I have checked the forum and know that this is a popular cam in a SBM. I know this won't be optimal in my LA360 but sounds like a good performer for my current combo. WITHOUT GETTING INTO A CAM SELECTION WORLD WAR....do you think I will be happy in my B-body? I use it for spirited cruising and twisty roads with 30% highway. Need somewhat decent fuel mileage (>15?). Need good torque (advance 268?). <6000RPM.
Yes I will need pushrods and yes I am concerned about the lifter quality.

Current mill has about 8000 miles on it. Runs great but down on power.
