Renewing all the other components that make up the valve train assembly will give a more satisfactory outcome.
Interfacing new parts with old will cause the new parts to wear prematurely and may lead to an unpleasant and noisy assembly.
This part, along with those listed below may be required. Adding as many parts as you wish to the same shopping cart makes good sense, as you will still only pay the same, single fixed price shipping cost.
Where possible always try and renew the complete assembly. Interfacing old parts with new rarely has a happy outcome! Have you thought about trying this pro-workshop gasket sealant - 08CRAHLG120G take your engine building to the next level!
