I will save you a lot of work. I had the milodon gaskets and they leaked in the rear, I tried two times with them. Now I am using Felpro rubber coated gaskets, no leaks. Good luck!

Did you line bore your mains? If so, your rear main cap will sit lower than the
oil pan rail. Use some peratex #2 form a gasket just on the rear main cap.
