T&D Rockers - Very Minimal Clearance between Rocker and Retainer.

Just setting up some 3128 T&D Rockers on my Brodix -3Xtra heads. I’m pretty sure I have the stands shimmed as close as I can get it to perfect.
But, the rockers look pretty damn close to the retainer to me. I realize that the rockers don’t move up and down like a regular rocker does on the stud when the pushrods flex at rpm, but I figure there must be some minimum clearance to keep the retainer from kissing the rocker body at high rpm, no?
Or am I being paranoid?
The pictures below might not be the best angle, but it’s not much more than what you can see there. Intake and exhaust respectively:

Great video! I wish there was a spintron near me. It would be very interesting to see just how bad things were getting under the valve covers.

Throwing that valve open another .100 how is he not going into coil bind? I assume for this test the valve train is purposely setup wrong but what if you are setup at .060 and you still get this loft over the nose? I guess most guys just roll the dice on this but wow. Thanks for posting this.
