Default Oil pan and cylinder head

Is it possible to remove the cylinder heads and drop the oil pan on '98 Astro, RWD without removing the engine from vehicle?
Thanks.

Yes it can be done with out removing the engine but since you are taking both sides of the engine apart it would be faster to remove to do the job.

Thanks for reply.
Actually, I need to pull driver side head off, and perhaps replace #5 piston, if my diagnosis is correct. Also I’m very limited on space, trying to do it in my single car garage, so pulling the engine is an option, but I hope that I can do it with the engine in place.
Do I need to lift the engine to drop the oil pan?<O</O
