Not Ranked
I compare notes with a lot of the other builders.
The FE that Keith built that went to 7000 with hydraulic rollers had titanium valves...big difference.
You're normally going to see 6000-6200 before you lose control of the valvetrain on a hydraulic roller FE. You can do things to extend that, but some of them start getting exotic....titanium valves....short travel Morel lifters with *solid roller* spring pressure, etc.
The Morels are pretty much the best you can buy. I've used a few of the other brands, including Crane, but I can't attest to where the pushrod seat is.
