Again ignoring pushrod angle against the lifter. A roller lifter / cam will produce side loading. Look at pressure angle.
While a roller lifter doesn't the max velocity limit of a flat lifter, at does have other limits. Again look at pressure angle.

Yep.
And they haven't gotten into the differences in lifter diameter, lifter wheel diameter, or what all of that will do to the rest of the valvetrain, like the rocker arms, rocker studs, rocker stud bosses......
As usual, a lot of people THINK they know. Then they'll be stunned at the can of worms they opened. They fail to understand, they do not want that genie out of the bottle, because it will NEVER go back in.
