The stock oil pan was reused. Always test for the oil pan to make sure that not only the rails are straight and not wavy and bent, but also for oil pump clearance which is often a minor issue with high volume oil pumps that hit the rear corner of the pan. Tightening up the oil pan without clearance can puncture the pan. If your high volume oil pump hits the pan, use a BFH (Big Freakin Hammer) to provide a little extra clearance.
This time around I used the Edelbrock Gaskachinch dressing to help set the gasket down to stay in place. This rubber cement glue works really nice for something like this.
To check clearance for the oil pump, no gasket was used. Clay on the oil pump was placed to see if it gets pushed aside when the oil pan is test fitted. With plenty of room, no BFH was needed. Now you can lay your gasket down and bolt on the pan.
