Hi guys does anyone know the thickness of the cylinder head washers?
Thank you

No I don’t, but it’s not a critical issue. Are you using domed nuts? Are they aftermarket or genuine? If you’re really concerned just double up on them…

@OllieDTR Not sure of the thickness but along with the cylinder base nuts and studs, these are fasteners worth buying genuine from Fowlers.
