Are the 2 bolts that go through the lift hook longer than the other 14 bolts on the 163 aluminum intake? If so, does anyone know how much longer they are? I found an original set of BB lift hooks and would like to put them on my engine but, I'm a little concerned about thread engagement at the lift hook because all 16 of my reproduction intake bolts are the same length.
This is from the ZL-1 engine assembly manual, should be the same.
