On the opposing side, I find a bit snappier and crisper initial throttle response from solids even below 5,500 rpms on the exact same type motor configuration. Two local friends just collapsed a hydraulic lifter on their cars... Pulling the intake for just one lifter...so this could be debated in different ways based on ones needs and desires - in my humble opinion.
I don't put a lot of miles on my car and just can't seem to get myself to get rid of the beautiful sound of solids radiating a bit through the aluminum valvecovers; Then again, I prefer black sidepipes and rollbars over chrome too. Sort of goes together, don't ya think?.
