That's a very large cam, It would most likely need the pistons flycut if you go with the milled heads. Stock heads and a more versatile camshaft and easy to set up valvetrain would probably be a better starting point for you if it's your first build
I'm not sure what your build goals are but that much duration and overlap is only going to run properly with very extensive supporting mods and a very very well though out complete setup. (Intake, fueling, and exhaust as well as the entire drivetrain need to be considered to get the most out of it and it's not something you can do one part at a time) Even still there will likely be drivability issues that you will have to life with in an optimized setup with that much overlap.

Yes the BTR kit and stage two cam is a great starting point its very nice go with that, You will still need to measure or check push rod length however unless it came with them, and it will definitely require some computer tuning to run properly, but once that's sorted out it will be very drivable. Do you have a manual or automatic?
