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.

I made the same mistake with my Magnum and LA oil pan. The flaps of the one-piece gasket hide the gaps left by the notches in the front on the pan for the timing cover. It leaked bad, especially when under heavy throttle. Took me a while to find it too. Here's some pictures of the issue.

I used a Cometic gasket set and really liked the quality.
