I have a set of heavy duty valve springs, and on the instructions it says once installed acceleration will be more responsive and the power band should be 200-300 rpm higher. If I install these without changing anything else is this true? Thank you

SBC's with fast ramp cams wipe lobes just as easily as the Buicks do. The BBC is no exception either. Go roller or leave in a nearly stock cam if you are worried about the lobes s hitting the bed. The springs were worth about 2mph on my old car which was stolen long ago with the stock turbo and 25 psi boost on an otherwise stock engine. Floating the valves could cause premature lobe failure itself.Blazer406 said:You are.... but Turbo Buicks for whatever strange reason..... have a nasty reputation for wiping out cam lobes...... if the spring pressure is too high (what would normally be fine on most SBC engines)... might be too much for the Buick..... and presto..... wiped cam lobe..... time for full overhaul then.....
Don't let me scare you off.... just be real particular what springs you install.
