Because you have pressure on either side of the headgasket slowly wiggling it back and forth. Mazda b2000's are known for this to.

Check the block and head for flatness.  If they ran it blown for a while, the combustion gasses shooting across the gap will actually cut a groove into the head and block.  Also, improper torque, you did lube the threads and hex end didn't you?

I've done lots of head gaskets like that, even with flat head/blocks.

i have had it happen to a few of my h22 gaskets oem honda too. i think it was bad/reused arp studs and poor torqueing on my side.  the surfaces were true also.    part of the reason i said fuck it and tore it apart.

I have seen a few mustangs blow in between cylinders but they were also boosted.... Some while trying to dial in with a btm and fmu... They would lean out with a little to much timing and blow between cylinders...

Detonation + path of least resistance, Jon.

Not that it means much for you guys, but this seems to be the path of least resistance in o-ringed and fire ringed Cummins motors EDIT: and the 3rd gen CR trucks that run factory MLS gaskets. Stock fiber HG's seem to be more prone to blowing out the side under the exhaust manifold.
