Cracked E15ET head

I have been running a E15ET head on a E13 block with impressive results untill it cracked between the exhaust valve and the spark plug hole on cylinders 2 and 3. is this common with this head or is it just down to the fact that the engine was running a high compressoin ratio?

I have seen a few crack over the years, but I wouldn't say it is common. Has this head ever been overheated or seen detonation due to insufficient octane?

No the car ran very well, but started misfireing yesterday. the head gasket was gone too, it had blown between the two cylinders.
