350 SBC Nova Motor

I pulled my nova out the other night for a nice Drive and it won't Rev over 5000 RPM. I pulled the Holley Carb apart to make Sure it was Clean, Clean as a New one. Changed Plugs and Wires, Cap and Rotor, Fuel Filter, ran the Valves, no Change. This Motor has Less then 3,000 Miles on it, I'm thinking maybe the Valve Springs are Weak. This Motor has a 7000 Rpm Cam in it, High RPM HEI and has NEVER had a Problem hitting 7000 RPM Before.

You may have bad gas I would try a treatment . Then if that doesn't work try a diferent spark plug. I've had same problem mine ended up being spark plug I as useing a dual head plug we all know splitfire then found out they will fry a hole threw your piston head .
