Safe way to lay sport jet on its side?

[fierodough]

I have a 2.5L 1998 Sportjet 175hp XR2.

I need so soak the cylinders in ATF as a last ditch effort to free the rings from the pistons. To do this I need to lay the engine horizontally for the ATF to sit on the pistons and work its way to the rings.

The engine is out now and sitting on a table. I do not want to sit it on its carbs. What is the best way to lay it horizontally without hurting anything?

Thanks!
