Hello, COMP Cams CL24-300-4 is what I would suggest if you have stock ratio rockers. If they are higher than stock ratio I would go with COMP Cams 24-278-4 since the rockers would increase the lift some. Since you are running such a high lift cam now the current valve springs will work fine. You will have to likely rejet your carbs down a few sizes and change power valves if you're running a Holley to a little higher number.

My goal is to provide 5 star service. Rating/accepting does not cost extra and ensures I'm credited for my time and knowledge. It also does not close your question if you have a follow up concerning this. Thank you for using Just Answer!
