Can you help with engine build?

Everything for your engine recipe sounds fine. Your cam is under the .450" limit for the stock Vortech springs. As for the specs themselves that cam is a just above stock mild unit that should work well for a low compression 350. The head swap is a win-win, additional compression for better gas mileage and power, fantastic low lift numbers and velocity for great low-end torque and upper RPM horsepower. i've swapped these heads many times two older 350s and it really wakes them up. Make sure you have the rocker arms to go with the Vortech heads as the later heads do not have guide plates. The valve covers are different, and there could be issues if you are running stock exhaust manifolds. The spark plug placement is slightly different so there could be interference with those manifolds. I'm not sure if the exhaust port placement is slightly higher possibly creating interference with the head pipes (?) maybe somebody can chime in here that have run stock exhaust manifolds. All of the swaps I've done had headers.

Only one time have I converted the early Quadra jet to an electric choke. Took the electric choke assembly from mid 80s unit from the junkyard and wired it up. I only remember it was a direct bolt on but I don't know if they are all the same.
