416 compression advice

Static compression will be set by the machine shop via the block and head machining. So you should be asking them or telling them what you want them to set it to. If the pistons are dished then a tight quench and small closed chamber will get you a hair over 10:1 static wich should be fine for the cam you're running. If the pistons are flat tops you need a biger cam. With what you have you should hit your mark with the EFI or a larger single 4bbl.. You may not reach it with the six pac. Those intakes are rather restrictive.
