Stripped threads in valuable intake- Time Sert vs. TIG and redrill or other

[KiWinUS]

Tim always consider what you are repairing. In you case a rare intake. You do not want repair to be visible. That rules out welding unless it’s a last resort. I personally am not a an epoxy guy. Band aid to me. Just my personal thought process as engines are not something I don’t gamble with. First for me is helicoil. If that won’t work then I would “keensert” “timesert”. Or as RR suggested step stud. Last for me is weld. I look at it as a process. If the first “ best choice “ fails use second option. I have used all methods suggested & above is how I would proceed with any antique speed equipment. Cheers
