I was thinking XE264, sorry. 216/224 .545/.555. I think those are the specs for that cam off the top of my head.
It may be roller, which will help a great deal with stress, but with a profile that steep, it's still going to side load those pushrods quite a bit. I'm not talking high lift, I'm talking steep lift. High lift is fine, with a long duration that doesn't make such a steep incline on the cam profile. Roller or not, the more sheer the profile, the greater the sideload on the pushrod. Without a roller setup, it would likely snap pushrods.
