It makes good practical sense to renew this item, and the other Valve/s as a matter of course when giving your engine or just a top end a makeover.
The more parts that are renewed in the engine the more reliable the outcome, and the time saved by not trying to regrind the pitted and worn originals can be best spent on other areas of machine maintenance - or drinking an ice cold beer!
Renewing this item will save time and provide a more reliable outcome! Are there any other parts that may be better being renewed than reused in your engine.
