oil pan gasket

Can I use a four piece oil pan gasket on a magnum block with a LA timing cover and a LA pan (7 quart milodon)? I know I can cut the one piece pan gasket at the timing cover and use the LA front cover seal with sealant and it will work, but can I use the LA set with sealant. I found out the hard way you can't use the one magnum gasket with the LA timing cover.
