Default Bolt length to head for engine removal

Pulling motor from top. How long do my bolts need to be to attach my hoist to the cylinder heads? I know the threads are m10x1.5mm but how long should it be?

Long enough to tighten down. I wanna say I used 1.25" long bolts when I put my engine into my car. I put a washer on the bolt and stuck it they the chain and tightened it down

I use four 10.9 metric bolts, two per head front and back. I also use a engine leveler. It makes adjusting the engine and trans angle so much easier.
