CHMOD Folder and Files recursively but with different values

Question

Is there a way to recursively change the access rights of a specific folder to 755 and files to 644 Without using the find function and having sub-directories in that folder (don't want to change those) ?

Currently I'm using chmod 755 -r folderName/

using find I think its something like that :

find /specific_folder/ -type f -print | xargs chmod 644

You can do it this way:

chmod -R a=rX,u+w folderName

For CentOs the command is:

chmod -R a=rx,u+w folderName

But it will rewrite subdirectory permissions. As the consequence: you cannot do what you want with just chmod.
