512 stroker for the street??

I'm building my first stroker and want to hear your thoughts and need advice on the build. The car is a 68 GTX 4spd with 3.54 gears. I'm looking to build a street friendly pump gas motor for cruising the back roads and burning tires. The block is a 440 that will have to be .040 to clean up. My plan is to use a 440 source kit 440.512.5075 which has -27 dish pistons sitting -.010" below the deck, Marsh performance sidewinder heads which are 84cc which should give me around 9.5cr, hydraulic flat tappet cam since this motor will probably never see 6000rpm, Edelbrock rpm dual plane intake, 4bbl carb, headders. 1st question- am I on the right track with this combination or should I use something different? 2nd question- what would be a good cam choice to keep it street friendly and have good torque? 3rd question- are the sidewinder heads a good choice or should I use a different head? I know this isn't an A body but there is a wealth of knowledge here and I appreciate any help I can get.
