I have made a big ooppssyyy 

I just replaced my freshly rebored barrel ans piston and it was running lovely

 

So i pulled the plug last night to check its colour and when put it back in finger tight and when i nipped it with the socket i stripped the threads  

I ordered a helical kit for 1.25 and done it today but when i went to put the plug in wouldn't fit checked the kit and they sent me a 1.5 thread pitch 

What are my options can i just get the right helicoil and tap and fit??

Might be a problem if you've use helicoil, the wire one.

Maybe able to use a timesert, I think the O/D is larger.

Only trouble is that thread in head will match coil @ 1.5.

Might be a problem after recutting @ 1.25  

Thats what was worrying me 

 

Think i might be better off finding a good head

If you have any contacts with a mill another possibility is block off the original plug hole and then rebore the head to a central spark plug it may be away to save the head and possibly get a better spark plug position.

well guys i spoke my neibourgh and he said before i put and insert in to let him take a look 

I had it back today and he said its done 

He brazed the hole a little and re drilled it and tapped it for the plug and it fits perfectly
