At one time I assumed all or most of the UltraDyne lobes were the same as the Voodoo lobes. Then Paul Carter corrected me within a post here at PY. That was much appreciated and with his explanations as to why they were not. A better design by Harold while at Lunati. I enjoy reading, and trust Paul's comments regarding the Voodoo lobes with his experiance using them, and his association with Harold Brrokshire. Seek out his posts on the topic. Or contact him direct.
That said, like many here I purchased UltraDyne cams from Harold when he owned and operated the origional company, and while he was at Lunati. Then later from Bullet Racing. Still a fan of UltraDyne cams
Keep in mind a engine will respond to additionl valve lift.
