Fred has you straight just make sure you roll to the exhaust side that way the shifting fork spline does not hit the ground. as for supporting it I used a wooden crate made to fit the head worked out well. Oh and the best secret I can give is run out to big lots by a rug and put in on the floor its much better on the old knees and you can roll it up and give it to the garbage man when your done.
below is a shot of it in the create next to the donor motor
