sorry mate
cant help ya

carl, just a tip, for the new forums, if you post things like this, they will be deleted.

yup, they look like normal nitrile valve stem seals.

hmmmm there are a few factors at play here.
1). do your valve guides have a groove to hold these on?? (if you have changed them, they probably will)
2) how much lift are you planning to run.. the problem with 3K valves (i am assuming they are double groove (ie BP)? if not ignore the folowing) with 2 grooves, is that the retainer is alot taller, and you are limited to how much lift you can run (less than 400thou) and my not give you enough space to fit the seal.
With the normal retainers, even high lift cams get a bit iffy as to whether you can run seals without damage

3) what is the inside diameter of the dual springs compared to the outside diameter of the seals?

4) what cam lift are you running (for reasons mentioned above)

5) i would suggest you dummy fit one valve with seal, and measure (accurately) how much lift you can run...then minus maybe 1mm and that is what should be safe Wink

6) ummm, get back to us when you measure things Very Happy

any chance of pics of said valves and valve guides?
