Those Vesrah gasket kits are just as good as O.E. Honda gaskets..,just a little bit cheaper.I purchased a few yellow colored background Vesrah top end gasket sets on Ebay for my CB350 twin,they're good stuff but the head gaskets will only work w/ bores up to .75mm over.I bored mine to 1.00mm over & had to get a head gasket from Bore Tech.
