I want to have enough cylinder head intake flow for a 360-380 hp, naturally aspirated, fuel injected 306 motor I'm building. What kind of numbers do I need? 220 cfm @ .500" lift, 240 cfm @ .500" lift or 270 cfm @ .500" lift? Can I use a aluminum head with a 1.90" intake valve or 2.02" intake valve?
