I was mentioning UD cams for similar short seat duration but the same 0.050 as the crower/041. Since the XEs may have problems why not use some UD lobes?
I used one XE in my TAs original motor when I freshened it a few years back. A custom one 262/270 on a 112 LS. I was not impressed much either and never got a valve tick out of it, the seat duration was longer than Comp said even at their own lobe lift. Similar motor with a Sunnit 2801 runs better.
