> Can someone explain to me the purpose of a torque plate?
A torque plate is a big chunk of metal that approximates a cylinder
head. basically, when a head is torqued down on a block the stresses
are such that the bores are a slightly different shape comparedto the
shape when they block is not bolted to a head. A torque plate is used
so that the block is stressed similar to having the head bolted on, so
boring results in a more accurately round cylinder with the head in
place, which is the condition where you want it to be round. Well,
unless you have elliptical pistons.
In short
No torque plate: bore is round with no head, not round with head.
With torque plate: bore is round with head, not round with no head.
