Bought a set of these today. https://www.ebay.com.au/itm/CENTAURO-TOP-GASKET-VFR-800-FI-1998-02-CYLINDER-ROCKER-VALVE-SEAL-EXHAUST-GASKET/272883817202?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649 For the price I think they are a good thing to have laying around. Top end rebuild is in the pipeline.
