Zach will post up, but the 110 seat pressure springs should be fine for 4000. He has had them over 5000 or more with no issues.

5000rpm is a breeze. But if you are going to stay there for extended periods, I suggest a good balance job, healthy cam profile, and better valves.

PM me if you have any other concerns.
