The 5.0’s heads and block are magnafluxed to detect cracks that
can’t be seen by the unaided eye.

Each journal is measured with a digital micrometer to assure
correct tolerances. This spec is the same for each rod. Each one
ends up the same size. Ditto on the crank journals — they’re a

The stroke of the crankshaft is measured to verify it is within
tolerance. This measurement will help to ensure that the piston
height will be correct for the rod-and-piston combination used.

Blocks, like heads, are magnafluxed to check for the tiniest of
cracks. Main caps are also checked for cracks. If cracks are found,
they are often in the lifter valley, main saddles, or even on the
outside of the block. Cylinder heads can crack between valves.
