496 fit in 1980 trans am?

i currently own a 1980 trans am with a 301 ci and i was planning
to swap in my 496 big block, im wandering if it can fit in there
and what modifications i have to make?

because looking at the engine width i wonder if the heads or valve
covers will touch the power brake booster and thus not fit :o

thanks alot for your help:)
