My engine storage prep for gassers:
* cover intake and exhaust ports, distributor, water sensitive sensors if present, carb if present
* clean and degrease
* spray down with WD-40 or other suitable water displacing lube
* remove spark plugs
* spray small amount of WD-40 into each cylinder bore
* turn over by hand using breaker bar several times
* if manifolds are present, store motor
* if manifolds were removed before sale, spray WD-40 into intake and exhaust ports as well (to coat valve stems), scrape manifold gasket surface clean, cover entire surface with blue painters tape then duct tape
* break off outer end of spark plug insulators and reinstall (this reminds me that there is oil in the cylinders and to crank it over then suck out remaining fluid before installing new plugs)
removing from storage:
* remove plugs, tape, covers, etc
* install
* remove spark plugs
* crank over, suck out remaining fluid, etc
* install new spark plugs
* fire it up and expect some funny smoke till the WD-40 burns off!
Of course some of these steps cannot be done for a compression engine. I would pull the injectors instead and hang tags on them to remind myself of the oil present in the cylinders.
