Just make sure to use a straight edge to align it with the rear of the engine where the bell housing bolts up, the important part is making sure the front and rear covers are aligned and level with the oil pan matting surface along with the pan to the bell housing matting surface and use a touch of RTV on the cracks where the front and rear covers contact the oil pan matting surfaces..
I think the tolerance is something like 0.020 cant remember for sure, but this pdf will show you everything for truck pans on page 11 or 172 & 173.. the Ls1 seems to be the same see pdf page 4... hope this helps

The biggest thing is to make sure the back of the pan isn't sticking out past the back of the block. When you bolt up the bell housing and pan is sticking out past the block you can crack the pan or bell housing. Just make sure you are even in the back. Put a little rtv where the pan meets the timing cover and rear cover so you don't have a leak.
