BBC Spark Plug Inserts

I stripped a plug out and installed a Heli Coil brand repair insert at the track but wasn't all that impressed with the repair. I was thinking of ordering the Time Sert brand kit. Are they any good? Still problems with the Loctite failing after heated? Or should I pull the head and have it welded and re-tapped??

Plugs are
14mm
.750" reach

 

Time serts are a really good repair. Did it on my chevy and it lasted quite a some time welding a head takes some time and will require a valve job or possibly new seats depending how hot it gets. I'd would use the time serts for the rest of your season and repair it in the off season.

 

Did you use the steel or aluminum Time Sert's?
