The cylinder in question could have a bit smaller combustion chamber if they were done by hand as opposed to CNC which could cause that cylinder to have higher compression. Also depending on what stlye of manifold you are using could cause that cylinder to run leaner. The Smokey Yunick book talks about tuning cylinder by cylinder. Get the one that is detonating to a good level and the rest will fall into place. If that requires you to retard timing too far back then something else is wrong.
You have to start somewhere and change one thing at a time.
