I know Cleveland Form Forged Irons are on the “Do Not Bend” list, but is it safe to use a .370 spiral fluted reamer and a drill press to change a set of irons from current .335 to .370 to accept graphite shafts?

Correction….current Clevelands are .355 not .335 as incorrectly identified….but I still want to ream them to .370 if it is safe to do so with a form forged head
