360 oil pan?

Use silicone around the radius ends. also use some silicone to seal the corners where the flat gaskets and the rubber gaskets meet.

Don't torque the oil pan bolts - they will be too tight and may split the flat gaskets. Just snug them starting from the center outward. Start out with just running the clearance out of the bolts, then go over them again and watch for the flat gaskets to start to "squish", then go on to the next one. Then go back around the pattern once after they are all tight and make sure that they still squish slightly when you tighten the bolts.

I like to use "gaskacinch" on the flat gaskets. It's like rubber cement and sold under the edelbrock name through Mancini racing. I use it on all the flat gaskets as it glues the gaskets in place before you put the parts together.
