    Lewis Tool for SBC Guide Slots

    I have been looking around for a prefered method of lengthening the guids slots on a sbc head and have found reference to a "Lewis Tool" in two places. Does anyone know where this tool can be found? or... do you have a good idea how to do a nice job quickly and repeatably.

    I have an old Goodson catalog that shows it - part no. CHR-16.  Don't know if they still have it.  I have done it with an end mill it my air float guide machine.
