The condition of the valves, valve guides, camshafts, cam-chain, tensioner & guide is critical for top performance and a smooth quiet engine.
When removing the head, check all those elements for wear or damage, replacing any suspect parts.
This component, and perhaps some of those listed below maybe required:
Add as many items as you wish to the same shopping cart, new valve stem seals 12209ML0722 valve retention cotters 14781ML0720 & tensioner gasket 14560KGH900 for example, and still only pay the same single fixed price shipping cost.
If you are going to carry out engine/gearbox/clutch related maintenance, then why not try this pro-workshop gasket sealant 08C70K0234M?
This component may have other, sometimes unrelated applications within the Honda model range, so please always check by the part-number rather than the description prior to ordering.
