I am building my sr20det with 86.5mm bore and 9:1 compression cp pistons. i am at the stage where the machine shop is about to start work and am wondering if i should be buying a torque plate? my understanding of this plate is that it is to compress the block as if the head were bolted on which causes the aluminum to squish a little and the cylinders to swell in a little. mazworx uses these while boring the cylinders and you are supposed to use one while grinding the piston rings.

do i NEED this tool? or are people building motors without it?
