318 LA engine timing cover/oil pan gasket questions

There are 273 and 318 gaskets, and 340/360 gaskets in that kit. In terms of the end seals - either will work, but if your pan has the holes I's use the 273/318 design that has all the nubs ([pictured laying on the pan). I use a dab of RTV in the corners under the end seal (between pan and seal). I leave the rest dry. Make sure both the pan and block are clean and oil free - including oil from your skin.
