The short answer is yes. Any time you remove the timing chain and camshafts you will have to reset the timing for the engine.

Here are a couple of guides that will help with this as well:

I am including the important parts of reinstalling the cylinder heads on this engine. I assume that you have a spark plug issue which is why you are removing the head. This was pretty common on this engine so please run through this info and let me know if you have questions.

Thanks
