On an average... how much pressure is too much seat and open pressure for a mild hyd flat tappet street cam? Say basically a 340 cam or a touch warmer cam. Slightly higher ramp speed but basically a 340 cam? Just curious what a 5,800 rpm street engine spring pressure should be? I don’t see a need to wipe a cam but also don’t want to float the valves at 5,300 either. Thanks guys.

9:1 compression
