Head gasket fail can you see the breach from th pics

[Davezj]

I am considering grinding it off.
But if it is the bottom of a drilled hole plug it might breach the hole.

Just wait and ask Head workshop guys when you be there for skimming?

[Davezj]

Yes that is probably the best option.
I was going through some pictures of Adam Findlay head work and he has ground off the little nubs.

FYI had the same symptoms as Dave, and similarly when engine was taken apart there was no obvious damage to head gasket, or head/block surfaces. Head bolts seemed on tight. Car was just recently (yesterday) put back together, not ready to tune it for high boost just yet, but I will soon know if the 11mm head stud upgrade, and head gasket job was enough to take care of the coolant system overpressure problem.

I hope your is fix by this as I only went for the 10mm stud option.

Only time will tell.
