Ratchet strap is easy. Just don't roll the engine too far forward, and start putting pressure on the radiator hoses.
I am due a plug change too. It's been a little bit over three years since I changed them. Guess I will keep on using the ACDelco conventional plugs AC R44LTSM since they have been doing good. New set of wires installed last plug change, so I hope they come off easy. I did use dielectric grease on the boots.
