I'm in the middle of a water pump replacement on my stock 305 for my 84 k10. This led to a timing cover gasket change to fix an oil leak which revealed slack in my timing chain (passenger side). I've never gone this deep before and never changed a timing chain set. All the videos I've seen are on engines that have been removed or being rebuilt. I've watched stuff about matching the marks on the camshaft sprocket and the crankshaft sprocket. Then stuff about turning 180 degrees. Etc. My question: Can I just remove the old stuff and put the new stuff on with the marks exactly where the old marks were at?

I am not upgrading or rebuilding anything. It's a simple remove and replace.
