First off I'm not sure if this should be TECH or General, but here it goes anyway
WTF are these? One bag of 12 and another unopened unmarked bag of 6. They appear to be the same parts.
Valve guide umbrella seals? These were in a box of parts I was given a few years ago, leftover GM dealership stick that was being tossed in the trash heap. Got these along with some c3 brake shoes and valve cover seals.
Would these still be worth using? Old tech? Should I buy newer ones?
These are metal with blue rubber with a little spring around them
Not rotten or damaged, still flexible. No rust or anything wrong
No idea if they are Viton ( whatever that is).
So, would you use them or buy new (if indeed they are umbrella seals)?
Thoughts?
TIA

Can somebody recommend a decent valve guide seal kit?
Stock gen1 L82. Don't know what size the valve guides are. I'd guess stock size, whatever that is. CompCams website lists many:
Lot of threads here re changing them, but none showing photos or part numbers.
I believe that's the style I went with but as it says, the towers need to be machined (to newer style head dims). My heads were out having the valves re-lapped so it was an easy decision.
Old style umbrella for a small block, fel-pro 10058 or Sealed power MV1598 but really whatever you can get at the local parts place
Part ID and application?
