I'd strongly suggest a hydraulic flat-tappet cam here. But there's a few things here that make me a little concerned.
An 11:1 street motor may not be as fun as you think for a guy that doesn't sound like he wants to work and tune it too much. Thats at the ragged edge of pump-gas capability, and if its not a race motor there's no need to push the envelope. I'd look to get it down in the 10:1 range for a street driver so you can put pump gas in it and have fun without constantly balancing timing and A/F mixture against detonation with 91 octane pump swill.
Second, a low-deck 496 is a short piston motor, that is not generally considered real well suited to long-life street duty. I know cubes are cool, but if its a non-race motor, I might stick with a piston that keeps the rings out of the pin-bore. I'm no pro motor builder, but I'd stop at 470 for a street only 400-block build.
Lastly, you've bought rocker gear before even knowing what type of cam you're going to use. A succesful build starts with a good plan based on the intended use. Based on what you said above (street only), theres no reason to spend money on expensive aftermarket rocker gear, as the stock gear will handle a plenty rumpety hydraulic cam, and will offer great street reliability, without having to be checked and adjusted periodically. If it were me, I'd sell the expensive rockers, and spend the money on a nice carburetor and perhaps a really good radiator (an 11:1 496 is gonna get hot in traffic!)
I don't want to flame, and I certainly don't want to stop the progress of a big-inch mopar build. I'm just being honest about what I see. Your car and your money though, so my opinion can be ignored fairly easily.
Whatever you do, have fun.
