I noticed it most at the front, but yes the back had a gap as well.

The area where the curve starts where the two piece gasket overlaps, on an la pan is pulled away from the block more than the magnum pan.

I didn't bother trying to tilt the engine the other way since I knew I had to rip it out.

Now I did check it after putting the new gasket on.

If I had to do it again, I would cut the front and back off the magnum gasket and use the la gasket ends.
