Alum Heads

Way oversimplified, but if the goal is power, and you are talking Mopar small block head choices, put the biggest port volume on it you can and cam it properly for your goal. There’s some subtleties to that but it’s a solid rule to go by if you done need to sweat initial investment and have a specific goal or set of goals to achieve. Mopar small blocks suffer from not having enough port or flow in applications beyond 1.25-1.5/cid.once you need more than that yu gave to spend a lot to get there. It’s a market/business thing, not a design or performance thing.
