Which all leads to - why do you think your head has cracks? ...and lastly- if the engine is running fine are you going to reinstall the head or a buy a new one?
3 Front holes are at .203
2 Rear holes are at .157
Bottom Hole at .126
Highest temp Ive seen is right at 1250f for a few seconds, and that is right before the turbo is spooled (running 16 psi with pump turned up by me)
Making a looooooooong pull temps sit at just over 1200f
the engine got hot a few times enough to boil water out of the reservoir tank that may have done it. that's the only thing I can think. I will acquire a new head and port it
