Best valve stem seals?

Hell of a job, so buy the best ones you can get

Seems elrings have good reviews on fcp euro.

Not sure if there's anything better lately?

I've bought these

Wondering if I should've gone oem.
Anyone has any experience with elring? How have they held up over the years for people who've done the job?

I also ordered a 90C thermostat from fcp euro, so hopefully lower engine temperature will prolong their life in the future
