You'll need a 351 specific intake, headers, and possibly a taller hood (to clear intake), all due to the taller deck height of the 351.
Here is a great article on the subject from Alternative Auto:

Note: there are a few options out there for the intake now, besides the Ford GT-40 piece...
Good luck!
