Are the intakes different from year to year?

No not really, the all interchange....There are very small diff. in flow numbers from different casting but nothing you would ever notice

I thought 93 intakes were a bit different than 94-97??

mdacton

it think the fuel rail goes straight across on the front, i'm not too sure

93s are definitely different than 94-97s because of the fuel rails.

You would be wrong there, common mistake though.
No matter how many times or how many of us post that the difference it the LT1 intakes is in extra material above the port rather than the ports themselves and that the LT4 head ports are not raised but rather tall this myth continues.

Here is a pic GIZMO from LS1tech posted, hope it helps a few folks learn a little something.

They're are 3 different LT1 intakes. The 93 intake which has a different fuel rail setup. The 94-95 intake has large rectangular ports, and the 96-97 intake which the ports taper inward at the top of the port.
