I wouldn't say OHC vs OHV vs 2v vs 3v vs v4 is any easier than the other. Depends on the application, any of them can be a bitch to do. The Lincoln Navigators DOHC 5.4 4v pays 3 hours to replace plugs, those aren't all that fun. Some DOHC's require the removal of the upper intake manifold or superchager just to fit an extension in the well. When the manufacture crams an engine into a mini van or cross-over, its a guarantee #2 bank plugs will be a bitch regardless of plug orientation.Draw back to through the valve cover creates another place for a leak. It's not un common to find oil in a spark plug well on an engine made by any manufacture with through the valve cover spark plug access.
