Replace the spark plugs and the cam, never use Bosch or platinum plugs in ford or any performance application. If you run the car hard it probably won't take long for the car to gain a miss as a result of the plugs. The cam is small for a 351, but it will work. If you are going to put a 351 in the car instead of a 302, I would want something that would run faster than 12s. It is easy to get a 302 into the 12s or even 11s on motor, a 351 car should run at least low 11s, I would want at least 10s. I had a friend who used a Comp conversion roller cam that had very close to the same duration and lobe centers as a E cam, but a lot more lift. That engine woud run out of steam past 5400 rpm. It ran 12.80s most of the time and I think a few 12.60s. The combo you put together should run in the 13s. Also you are right about the carb, if you have stock heads and an E cam you would be better off with a 650 carb.
