LS1 block after being decked with our True Deck fixture and Honed with a torque plate. Contrary to internet rumor these block NEED to be honed with a torque plate as the bores do move around from head bolt distortion.

Torque plate honing Difference

Peter Graves — Sat, 31 Oct 2009 19:36:31 GMT

Not really sure if Torque plate hone is worth the extra cost? The dark shadows on this BBC are where the hone does not hit when the bore is distored by the head bolts and gaskets. How well do you want your engine to seal?
