Here are the results of a blown head gasket that was not addressed in time. As you can see, the stock head bolts broke off during disassembly. The head was stuck to the block and it took quite a bit of force to pry it apart. The heads and block were trashed. Still, it was nice to have them around for extra parts and as an example. In hindsight, the Benhams wish they would've stepped up to head studs before they did any performance modifications.
