It will bolt up to any 300 or 240 block, no worries, and all the stock or aftermarket intake/exhaust manifold combos fit as well. The chamber is smaller than a 300 head so if you're building up a new engine from scratch you need to be careful with piston choice and the amount of machining done to the block.

The injectors fit into the EFI lower intake, not an issue with a carb intake manifold.

The EFI heads have fast burn combustion chambers. So you might have to pull some of the timing advance out. The fast burn requires less total timing.

Won't be needing those, pipe plugs will take care of that.
