Can anyone suggest the best overall cam and headers for a olds 425 engine ?

 

How are you using the car? Is it only the street and a cruiser or are you planning on racing? What gears do you have? Heads? Compression ratio? Stock intake and carb? What trans are you using? These are all things that will be needed to give you decent advice. Is it 39 or 45 degree cam bank angle? What size lifters?
