the prob could be shabby tolerance on the drill and tap, or just the milling on top of the head where the plug seats... you got a mill???

if it's not real bad it will probably plug itself up! lol
Good luck
Unfortunately no mill , I'm glad it's no great issue was worried it would decrease power or similar ,it's amazing the difference a good quality plug does make compared to the kit original ,was going to try the iridium ones but at $42 for a single plug stuff that .
Thanks for the quick reply Rusty ,much appreciated mate
