I have the S&S lifters on my bike, seem to work fine. Also, when you have your gear driven cams installed, consider installing an S&S reed valve at the same time. It will correct any oil blowback coming from your air cleaner. It's a simple install while they have the cams out.
Use the stock lifters. They will work perfectly in just about any engine no matter what mods have been done. No need to waste money on more expensive ones unless it's a race bike. Even then, I've built some 100+ ft lb engines that I raced every weekend for a few years before needing to replace them. Those were some HARD miles and they held up great.
