correct way to store cranks and heads

Cranks standing upright, heads block side if room(intake side for saving space). Blocks on bell housing face. Do not clean. Grease machined surfaces. Bag in heavy trash bags. Not going to fight anyone, just the way I've always done it. No problems.
that's what I have always done. only thing I am considered is making a "double rail" where I would hang them from flywheel end. ????? .......
