Having been off a few rotations on both right and left cams, how would I make sure both sides are at TDC? Should I remove spark plugs at 1 and 2 ('05 V8 LS430) and do the screwdriver trick? 1 should be topped out and 2 should be bottomed? or both topped? Read the whole thread and a few others on other forums and hope I haven't done real damage so far. Right cam snap-rolled forward and I couldn't rotate it back. Found it can turn forward easily and snap-rolled 2 more times back close to original timing. Then I tried to rotate a little more but it kept springing forward. I must've had it done 3 rotations before I tried fiddling with the left cam. Same thing happened and I lost count how many revolutions. I eventually got the belt back on at 0 marks with correct belt markings (oem). But turning crank by hand, it definitely feels like there's resistance and even bounce (springing back or forward when letting go).
