Thanks for all the great advice. I have had it installed for a while now. I used a thin film of rtv on each side of the gaskets and carefully aligned all 4 pieces (gasket/tray/gasket/
oil pan). I then snugged the bolts and allowed the rtv to set overnight. Then, I tightened them a little more. I believe it will seal very well. Everything so far has aligned without any problems. I used the crank spacer to center the timing cover as I have read here and in books. No dowel pins on the front cover sucks and is a bad design. I am still waiting for my Crane valvetrain to arrive. Should be son I hope. Todd
