well, they actually used both - because BMW couldn't get enough hollow formed cams built at first. It just depended on what happened to be available at the time your engine was built. Some engines even had one hollow and one solid cam (the one that came on my parts engine for example). My 330i has both hollow.
BTW, Pete shared with me the cam cards for those regrinds - they definitely got the profiles mixed up. I think they thought E = exhaust, but it actually means einlass (inlet).
11mm of lift would be good but I'm not sure a 268 duration is enough. It really depends on what the duration is with MILVS - the only real way to measure that would be at the valve itself.
