Are you serious?
you want *files* that you create to have *execute* access by default?
Sorry, can't be done. The kernel default for permissions is...
on directories: 777 (drwxrwxrwx)
on files: 666 (-rw-rw-rw)
the only thing that changes this is your umask, which withholds certain
permissions. It cannot *add* permissions that would never be set.

as a normal (unprivileged) system user, your umask should be 0002, which
will result in permissions as follows:
dirs: 775
files: 664

not really. If you *really* want to change 1000 files so that they have
execute perms (and write permissions for group) then you can use a
recursive chmod command:
chmod -R 775 /dir/containing/files
or more appropriately:
chmod -R a+x /dir/  (your files should have group write set anyway. The
default umask does not prevent this)
if it is only a subset of the files and dirs you wish to change, you
could use a 'find'command (optionally piped into xargs) to run one of
those chmod commands on only the files you wish to alter.

When you upload files to the server, they are *newly* created files
there, and will get the default permissions on that end as well.
you could of course wriute a small shell script that runs the chmod
commands you need and run it on those files after the upload. You
clearly have shell access on the remote host (otherwise you wouldn't be
able to manually change permissions after upload).
Do you have ssh access? you could use rsync, which will use ssh for
transport and can preserve permissions and ownership.
scp -p -r /local/dir remote-host:/remote/dir
will do similar things.

Have you considered packaging your web app as an RPM? You can set
default permissions for every file it contains if you do this.
It will also give you pretty decent version control.
