The cams all have about the same duration-the difference in opening deg reflects the amount of retard so you can see how much it varies. The 02/03 cams are dual pattern cams with more lift/duration on the exhaust. I think they are very similar to the cams used in the 300hp version of M117. The 300HP 5.6L will propel a 4200lb car to 60mph in 7s with 147mph top speed with 2.65 final drive ratio-not too shabby for a 2V m117. If you are looking for more cam I would be looking at the long stroke M117 cams.
I cc'd the 3.5 heads at 39cc and the 4.5 at 45cc.
What CR are you running?
