Caustic soda hot wash, available at a cylinder head specialists, the less effort put in the better IMO

That is caustic soda, but its how its used that does the job

Doh ok, machine shop it is then i suppose i do need to get them re seated at some point so might as well do it as one big job.

Thanks

I'd mix the soda with water in a plastic bucket put some rubber gloves ( Very important)!!
Do NOT handle caustic soda without rubber gloves

Then wash each valve seprately with a scourer. Should come up nice a kleen.

The regrind the valve seat with some grinding paste.

get a drill. put the top of the valve stem in the chuck then spin it round while holding some emery tape on the carbonised bits.........

That's the quickest and easiest way!

Just mind out that you avoid the the valve to seat contact surface!

This is what I did as well, the really badly caked stuff on the exhaust valves I used a sharp knife blade in parallel with the surface to get the initial rubbish off, then increasingly finer wet & dry (360 - 1200) and a finish off with metal polish

Pleeeeeease buy some goggles if you're dealing with nasty chemicals too!

You only get one pair of eyes but I'm constantly amazed by people's cavalier attitudes to eye protection!

Risk assessments and health and safety have been the pain of my life lol.

tell me about it but when you are surrounded by turns and twirlys (no offence ment to anyone) you have to be that extra bit carefull!!

Not really,,,,,, dumping it all in a hot wash and returning 30 mins or so later to minty clean valves is much easier IMO
