How is the block not going to like that any different than a comparable 440 built the same way? You can get wedge heads that flow the same as his stock conversion stage v heads, after that the rest of the build is a wash. If he's going for high hp and high rpm he may need stuff like aftermarket main caps/studs, block girdle, etc. But it's not like a 440 has never been taken that route before. IMO it depends on what his overall hp goals are.
