Can I fit resistor plug caps (say NGK LB05F) to non resistor NGK B8ES PLUGS ? Cheers all

I think they’ll work okay, but you can take the little resistors out by unscrewing the inner brass connector (the bit that fits to the spark plug) and remove it and use a short bit of metal to replace it - you can cut up a small bolt or similar.
Careful not to loose the tiny spring!

Yes!
As long as you have only one source of resistance you are ok.

I thought I'd been using those caps and plugs all the time and just used them as they were.
