If the block was originally done with a plate, it should be redone with a plate. Shadows in the cylinder walls if the block is thin. Good luck. Dyno

talking about honing your block, my machinist bolts up the plate & then puts the block in the oven till it's hot & then does the final hone. is this a common practice? i'd never seen a block being done until i stopped in for a cold one just on xmas & saw one of the boys doing this, was told they do this to all torque plate hone jobs.

The plates help keep the cylinders round after the heads are bolted on. Some shops bolt blates on both heads, torque the main caps and run hot water through them! Helps ring life and seal.

FWIW, years ago i had a 440 block bored and honed with plates. Pulled it down and just had a de-glaze done to re-ring. They didn't use plates for this. Ran pretty much the same ET (sometimes slightly faster, sometimes slightly slower). Nothing that I can pin to the plates.
It's always best to use them for any honing operation as it's proper procedure.

Touching up the finish with a ball hone (Flex hone) is a completely
satisfactory practice. Since it followed the same contour, it didn't
change the shape of the cylinder and when the heads were torqued
down it returned to it's original cylindrical shape.
