Ummm not sure. My guess would be that the injector is letting part of the combustion process past the seal and this has heated the head... not sure...

The only thing that has caused that is excessive combustion temperatures
nothing more nothing less no excuses........

Personally Id say new head time Klappers and I wouldnt reuse those valves... by internet picture judgement anyways!!!

I wasnt going to reuse the valves.. I was going to get the head serviced and let the cylinder head experts make the call as to whether I reuse the head.
New head = 1300 delivered

Klappers,Great photos........pity about the subject.I hope the $1300 is for a new head ready to be fitted.If it is just the price of a bare head check out my post http://www.aulro.com/afvb/discovery-...soft-head.html Turners are very good to deal with,I spoke to Freda on the phone,great advice.Make sure you bleed the cooling system thoroughly.....takes a few goes!!
Turner appear to be quite cheap ehh.. 295 pound for bare head.. thats not bad at all I say. Cheaper for me to purchase one of those then risk my head..
okay.. bit of an update. I have sent Turner an email asking them if they can give me a price for the bare head and head gasket and studs.
