Damn, I used to know this off the top of my head. How we forget things with time....

Realize you will not get that much gain from cams relative to cost. The major issue with the V12 heads (Ed feel free to correct me) is not so much the duration, but the exhaust port design. It really is the limiting factor even more so then the dual valve design!

I know 8eights has had both head work as well as high lift cams installed in one of his eights (no pun intended). He can comment on the results from personal experiance.
