1936 Packard 120 B cylinder head repair

Yesterday I was warming up my 1936 Packard 120 B ( 282 ci straight eight) when I heard a loud pop and shut off the engine. I opened he cowl and found that my number 2 spark plug had been blown out of the cylinder head. Further examination found the threads stripped on the spark plug. I tried to install a new spark plug and of course it won't screw into the head becasue the threads in the head are damaged. The car has had these plugs in for 4 years with no issue. Now what do I do? Can I get the cylinder head spark plug hole repaired or do I need a new refurbished cylinder head for my 36 Packard 282 ci engine? I am in Naples, Florida so anyone know of an engine builder or machine shop in South Florida for repair please forward the information to me. Thank you in advance, Dean.

Google helicoil spark plug repair and you get a lot of results. Seems like something any competent machine shop can handle.

A HeliCoil kit would be the fix for sure!
