All,

I would leave the piston down slightly so if you have to drill out hole at 
all you won't damage piston. When done with tapping out helicoil threads 
start car up leaving out helicoil & rev up slightly. This should blow out 
aluminum or iron pieces. Also put heavy grease on tap threads to minumize 
pieces that fall into cylinder. Clean threads with carb spray & let dry after 
this then install helicoil with a thread locker like permatex brand to the 
cyl. head. Let sit to dry then install plug with anti-sieze compound. That 
should do it.
Good luck!
