ebay viton valve seals reviews?

[Guest]

So I saw some other threads on this subject but none seemed to have a conclusive answer as to whether these ebay viton valve seals are legit or not. I decided I should probably take the time to renew them since I've got the head off the 550 anyway. I ordered some the other day just waiting for them to come in, but I won't do it if people have had trouble with these. So what I am looking for is a thumbs up or thumbs down from anybody who has experience with these particular type of valve seals. I attached the picture from the ebay listing for reference.

I have them in mine, no problems so far (7500 miles). They are what Z1 sells

They are good seals & I use them. Ray.

Okie Dokie Guys,
Thanks for the thumbs up to commence. They came in the mail today so I'm heading out to finish taking the valves out and start replacing the seals...
Any tips on cleaning valves at home?

A wire wheel on a 6 inch bench grinder works well. Ray.
