Best Method of Sealing Timing Cover/Oil Pan

I don't know of any one gasket that covers both. But the best way I know of
is. Install the front cover first. then use a small dab of silicone sealer where
the pan gasket meets the front cover.
If any one knows of a late model rubber gasket that's fits the old style LA
blocks let me know! I heard of this but can't figure it out myself. I know the
GM small blocks have a set up like this and it works well.
Come on guys. Lets help him out!
