High rpm FE's have never been a problem. High rpm hydraulic roller FE's have been the bottleneck.

Lots of my customers want a little more rpms without having to run a flat tappet cam or the risk of a solid roller. Now we have options.

I took it to 7500 simply because I wanted to prove my rocker arm design. It went there very easily with only 200 lbs seat pressure and 500 lbs open.

We turn 8500-9000 rpms with <400 lbs seat pressure and 1200 lbs open pressure on my BBF pulling truck engines.....with almost 2.5" valves. The right cam lobe makes all the difference.
