the v6 lid is off to the side a little more than the ls1 lid.

you could modify an ls1 lid to work on a 3.8 ive seen it done, but wouldnt recommend it. somewhere a long the line you will lose horsepower because the air flow wont be as smooth

I gained 1.5 mph from k&n to the lid and everyone says every .1 is 10hp but highly doubt it added 15 HP
