You need to check all your timing stuff against the pelican DIY, make sure the main chain cog on the exhaust cam is clocked properly, make sure both VANOS cogs are clocked properly, check the main chain tensioner and timing chain tensioner, make sure the VANOS thrust plates are facing the correct direction and that those bolts aren't over torqued. If it's running really rough I'm guessing its the main chain off a tooth, make sure the block and cams are at TDC and re-do it.
Also before you tear it apart again make sure you didn't leave a vacuum hose loose or something that could be causing the roughness, it wouldn't explain the sound but it's worth checking.
Did you cover your cams/the VANOS assembly in oil before putting the valve cover back on, if not maybe that's contributing to the noise.
