Small Block Head Flow Chart

This is like when I had my heads max wedge ported. On the porters bench mine started where most others topped out at. Then mine were 60 cfm or so better. Well we know that no one else ever got these big numbers. They sure looked mighty good. The percentage was 15% better from where he started. That’s about right for the port. That’s why u can’t race flow benches. Not many benches would read the same. Kim
