360 Heads on my 318?

I was offered some 360 heads by a friend and i am just wondering what i would have to do to put them on my 318. I already have an edelbrock performer 318/360 intake and the engine has an unkown cam installed by the the previous owner. Is there any serious modifications i would have to make or would i be better off just staying with my 318 heads. i guess i should also mention i have a burnt valve so im going to be pullling the heads off either way.
