If using a genuine Yamaha RD350LC head gasket do I need to use any jointing compound ?

even with pattern gaskets have never used sealant on a head gasket.i have forgot to give them the final torque so when I filled the rad up the gasket leaked, but fixed with another nip down.

Permatex Copper coat HG spray OR Rattle can Laquer (no substitutes ;-)..Clear or the colour of yer choice.
It Works.. period. Also ideal for repeated HG reuse.. if..the gasket is of metal.

I tried with and without sealant and it leaked was,nt till I gave the head a light plane that cured the problem.I think the other thing is not to forget to give it a second torque up once its been ridden

Is that also the same for a YPVS 350 metal head gasket ?. If so, any chance you could put a link up to the exact correct ones of these to use, as I'm just about to try to re-use a genuine head gasket  I found the Permatex Copper Coat but I can only find it in the US and they won't ship it to the UK ?.
