The pushrods won't allow that to happen The better you control the side movement of the rocker arms the more net lift the valves will see :up BTW, to get the best setup on each rocker arm location you may need to shim the other side of them also Another reason why I call them Hemiroid motors

FWIW...my 572 hemi has had the stock style spring setup on it since I built it in 2006. I will be changing to the clamps at the next freshen up b/c I'm curious if they'll help w/ valveguide wear.
You can see my setup here...my daughter was "helping".

Looking at how light those springs are, I would think that my bad luck would cause the rocker to walk down the shaft and fall off the valve tip, resulting in an immediate and expensive failure. But I guess that really doesn't happen???

Dick Landy claimed that the collars added horsepower by stabilizing the valve train. I don't remember how much.

Anecdotal evidence and opinions don't cut it these days, and that includes my own. We need an episode of Mythbusters featuring the 'ole 426!

Look at the way the pushrods are angled. They side-load the rockers into the stands, not away. Spot on right there.
