I cannot get the lifters' plunger to move at all today - trying to readjust the rockers is pressing on the valve spring rather than the lifters - this is happening on all 16. This is happening right at zero lash, the valve springs start moving. Shimming and stock pushrods are doing the same thing. I'm thinking of putting the Melling ones back in and giving them a try, rather than these "High Energy" ones.

The Comp high energy roller lifters are essentially Ford OEM lifters, aren't they? I bought a set those for $100 on Ebay and I couldn't tell the difference between them and the original Ford roller lifters.

I'm surprised you're still having a lot of noise, though I did have to adjust mine 3 times before they were quiet - I think it's probably the Crane 1.7's that are most responsible for the noise.

Yeah, according to Comp Cams, they're very similar to OEM. I don't think I can get quiet without different rockers, roller or stamped.

If you ever find a roller rocker that is as quiet as stock, let me know!
