the runners are slightly different, its something like .1" difference so if you wanted instead of having to spend $800 on a used one on ebay just find a good shop and have em modify the current one to accomodate lt1 heads, that or just go single plane

The 1997 intake has almost identical ports to the LT4. It just doesn't have the extra material above the port.

I've compared them side-by-side and saw that ALL of them have almost identical ports. The LT4 intake has more material above the port, which allows them to seal up to heads with large runners, like AFR 210's, and also allows more porting.
