right long story short.
ordered a set of stem seals.

got them today (took a few weeks) and the supplier sent me 16 12210-pz1-004 stem seals

every other time i have always used oem honda but i get 8 with light springs (as above) and 8 with dark springs. will these stem seals last fitted to the exhaust side or will their life be compromised due to the exhaust valves running alot hotter??

thanks!
