Thread: using a torque plate

1to the mild part of the bores can be off as much as .003+ so it is out of round so it can pull the bore out of round making both hi and low spot in the bores you will have to hone to the low parts of the bore to get it back round this is hard for the rings to seat up this has alot to do with how thick the block is and how many head bolts are around the bores if it has had deck plates on it when hone the bores it top could be out of round if check with out deck plate on the block if not hone with deck plates and you hone it you will make the bore bigger by taking the hi spots out and were there is a hi spot so you will have to make a round at the point where you will make the hole bigger to get the tapper out to you just can not hone the top of the bore and call it good with the deck plate on. the mains should all ways be TQ up when honing the block out with or with out deck plates from boring to honing with deck plates on a engine when boring you leave more in the bore to hone out less you bore with the deck plates thru the honing to i leave about 0.002 more in the holes when i bore if i going to use a deck plate you have no idea what the bore will do with the plate QT down i seen them move were you would not think they would get out of round
