Just had some work done on my 416 which required the head off and valve seats re-ground, one thing I'm not sure about is, is it worth now changing the spark plugs or are the old one's still ok to carry on using?

When were they last changed?

Only about £15 for a set of NGK's anway.

Good question, I'd take a guess at September time.

Yeah, just give them a clean and check the gaps.

what's the best thing to clean plugs with?

It's best not to clean plugs unless they are very dirty, which they should not be. Don't use a wire brush as this can leave metal deposits on the insulator. You could chip any coke off the side electrode then file the contacts with a riffler file, but I would leave them alone.
