I recently did a set of gt40 heads for a buddy and I took the freeze plugs out for those.... never noticed any in sbc heads. Is there anything wrong with the way I did these? I used 20/40 media switching to something a little easier on it
Edit: Also that crack checker says non ferrous metals so would that be cast iron heads only? no aluminum?
