Kevin, I just did mine. I used gaskets between the plate and engine and oil pan. Could not see metal to metal sealing too good (Jon Slade can testify to that). Dry run the whole thing with the oil pickup tube installed. I had to manufacture a 1/2” spacer to compensate for the engine mount plate thickness. Than again I had some oil pickup interference that I had to correct. I safety wired the oil pickup bolts and used lock washers on all the oil pan bolts.
Another thing: I did cut the oil dipstick tube also to compensate for the mount plate thicknes.
