hydraulic roller lifters issues

If you have 1 lifter that "peaks" out at full lift, I dont really see it as an issue. Its there for a nano second, and only 1 lifter. Its not the best for sure, but if it just barley peaks out, I dont see it causing a big issue unless its out for more than a "peak". Do you have pics????

I can see it causing an issue if it looses pressure and collapses, but it really is there for such a short period of time.

No, I never took any pics when I had the cam in the block. I afraid it would noisy if I used it the way it is. Is here any other hyd roller lifter that would work. Not sure how much of a difference it will make in HP if I go to a hyd flat tappet
