With as good a results as the Ultradyne cams got, even with Butler using them as his main go to cams(before Harold and the IRS got sideways and shut it down) I still don't know why more guys are not still using them. Bullet has them even Lunati has them as Harold did a tent there(when I got the 296/304 in my pump gas motor).
FWIW with an US 304/312 on a 112 in my RAIV 400 Rhoads did not help vacuum any or improve bottom end and even regular lifters ran power brakes fine. They were so noisy , and would bleed down even when trying to set them(start at zero tighten more then it would feel almost as loose as at zero from bleed down) I replaced them.
