Plug gap isn't critical. Anything from 0.6 - 2mm will work. Guaranteed. Its all a myth....

Yeah, just give it a tap, but dont go mad or the earth electrode falls off into the engine.... no one wants a bit of metal bouncing around in a cylinder. Do a test and see how big a gap the spark can jump- about 30mm on a dry day (screwdriver to block). But the compressed fuel air mix does block the spark to an extent, so i generally max out at 2mm even with a high compression engine.

thanks for the input guys but really wasint wanting to just fire them in with anything up to 1.5mm out possibly, a was thinking 0.9mm but again thats just a guess from what i read on the internet which is basically zero
