When I went looking for a 2bbl manifold, without egr for he 360 in my 65, I had to lift it off the block and slide it up over the radiator to get it out of the raised junkyard truck by myself (6'1" 170lbs.). Then when I put it on the 65 I used a 6 foot 2x4 with the manifold suspended in the middle and me on one end and my wife on the other end. By the time we lowered it onto the block it was getting dark under the hood but we managed. Used the standard cork end gaskets and got a perfect vacuum and oil leak free seal. Hopefully if it is on the ground one is good with dead weights lifts...
