 Most folks just bore and hone the block, right? This miraculous little secret shows some very detailed engine work done by the best engine builders ever, Mike & Bob at Accent Auto in Blue Spring, MO. First, to achieve .30 over, their boring is fairly straight forward where .25 thousandths is bored (off camera). The remaining .05 is removed with this ‘Honing’ machine's series of many stones with a ‘Head Simulator’ that is torqued way down to the block, replicating "out of round" of the cylinder's walls deflect when studs are torqued down around each cylinder! Don’t believe those head bolts would make the cylinder "out of round" You can physically see the oil streaking down paths on  the inside of the cylinders. 1) Bore=perfect circle;  2)Torque down head=distort that perfect circle;  3) Hone with Simulated Head and get your perfect circle back! Yep, once those head bolts are torque down, they sure did distort the cylinder! 

Is your C2 headlight motor giving you are hard time? How do you best access it? Test it? Fix it. A must see video!
