It's a 1098 and I've actually got a 940 head that I bought a while back (with a view to boosting the engine's performance a bit) so maybe that's the way to go. Is there an idiot-proof (or at least idiot-with-some-reading-proof) way of telling if the head I've got's in decent nick or should I take it to a professional for their opinion?
I had thought I'd better beef up the brakes before installing a more free-flowing head (and have some Wolseley drums and backplates in a box waiting to be rebuilt with this in mind) but do you think I could get away with just doing the head swap and taking it easy for the moment?
Does anyone know if insurers get aerated about 940 heads on 1098 engines? I know it's a popular upgrade on here so maybe someone with one can say?
