Sorry to keep bumping this lol. But it looks like it's going to be real close. The lip starts at 1"3/4. This picture is the best I could get.
In the mean time I will see if I can find a riser. If so I can get the WRX bolt that is longer and raise the lip up a bit. Either that or I bust out the dremel and remove that lip all together.
This solution will perform the best since you won't have to worry about over cooling your oil in the winter, and it will bring the engine oil up to temp faster. Win win.
