[Fot] TR head cracks

[TR4 Tony]

All

Have we not got a head that's getting to the point that it's not worth a
repair - new cast iron heads are available and very good indeed. Used heads
are still around.

I'd be loathe to throw the same amount of money at a marginal head that I
would at sorting a good used one or indeed twice that for a new one. Most of
the repair techniques will deal with small issues but this sounds like it's
significant, even in this location which normally isn't such a big deal.

Regards

Tony
