I recently acquired a 272 Block for parts, and just for the heck of it, but it was seized. I popped the heads off and the first thing I noticed was, one of the long head bolts was not on the end of the head but in the middle of cylinders 6&7 on the drivers side. On the passenger side it was similar. Anyway looks to me that the incorrect location of the long bolts on the drivers side caused it to seize by head gasket failure.

What do you guys think?


Drivers side


Drivers side head
