Fred,

I think just 6,000-6,300 for most power would be fine. That's probably the most RPM the valves springs can take for the ones that came with the Edelbrock heads, and it is towards the top of the range for the hydraulic roller lifters. No question though that the heads, intake and cam can do all that on a 289.

John
