Magnum oil leak problem
I know this has been discussed before and there are opinions on both sides on using the magnum oil pan gasket or the LA. You're definitely not "supposed" to only use the magnum oil pan gasket. Either one works, just one requires extra sealer. All I know is that the LA works as it's intended to, without any "extra sealer". Now I do like the later one piece gaskets, but didn't want to run into the problem you're possibly experiencing because I didn't do the "extra sealer" part right. I've never had a problem with the LA oil pan gasket on my magnum, or any previous LA motors.
