Topic: Top end gasket set

[GeoffT]

Looking on DS Spares at top end gasket sets for my  F1 550. I was assuming that the same set for the 550 and the 500 are the same. However I notice that DS listing for exhaust port gaskets are different prices for both bikes (and part numbers) can anyone tell me what the difference is if there is one? 

Also any thoughts on advantages/disadvantages for NOS gasket set compared with new pattern one?

The original 500 head gasket was a smaller hole but even Honda superceded it to the 550 one, exhaust gaskets in the ports will fit either although the style was changed. Whichever set you get make sure that the "pucks" over the bolt holes are in there as Honda started selling them seperate to keep the set price down otherwise whichever you can get easy is probably the best
