Subject says it all...bloody annoying!

It's been about 6 years since I had a "reputable" workshop carry out the ls3 conversion in my vx and after changing the spark plugs over the weekend I found they have forced in two spark plugs, one in each head. The spark plugs seemed to have dodgy threads and it's pretty obvious when you try screw them in.

The new plugs do still screw with a wrench with a little extra effort however they dont seem to get to that tight point. As these are Higgins porter heads I a hoping they can be fixed without helicoil. Any advice would be much appreciated

The only thing that could be done depending on damage would be to run a tap down the thread to clean it up, but if not done right will do more damage or push swarf into the affected cylinders!
If it were mine, heads off & trot them back to your repairer or Nathan the man who built those heads.
