Picked up a set of HyLift Johnson 0951 lifters today after dissatisfaction with 2 sets of Crower lifters.
The Crowers sounded awful in the 455. I tried 1/2 turn from zero lash and 3/4 turn from zero lash, and they still sounded awful. (HarlanSharp 1.5 rockers, round port Eheads)
Fortunately TopLineAuto had a distribution center just 40 mins. away and these were in stock so no waiting for shipping.
I was in the middle of pulling the motor for an oil pan leak, so the time was right for a change.
The HyLifts were about 2X the price of the Crowers.
The most obvious difference between the Crower and the HyLift is that ridge just below the oil hole.
Crowers do not have that ridge.
It does not extend to the full diameter of the lifter, but I am not sure of it's affect.
