Pretty sure the magnum gaskets have the oil hole also. I used magnum Felpro 519SD's on one of my strokers that had LA Heads & Block. I did this because the compressed thickness was .054 "pistons were out of the hole" The block is where the oil is restricted for the Magnum's, not at the gasket. "block is not drilled to supply oil to the heads"
thanks for the info louis i was not 100 percent sure on this as i am not right familar with the magnum engine but i should get my facts straight there is enough bad info out there.
