No sorry. They were probably bent. The inlet valves set was only £150, so I would be surprised if you get a set made for that.
It's the exhaust valves which seem harder to obtain and are about £140 each. found two reliable importers of beat parts. nengun and JDM. now i requested a quote for all the parts I needed, you should see the parts on their website or eBay. I used JDM on eBay. They do reduce the combined postage but best to email them with a shopping list and agree combined postage upfront if you can. Don't forget approx 20% duty and £20 royal mail handling charges. Maybe work buying a new exhaust valve and see how much it would cost to copy. I may buy another set for the shelf.
