Actually they are drastically different in flow than the factory stuff. I have a set. Trick Flow has been making copies of hump heads for years, and doing a really good job at it. Paint them orange and they fool everyone.

Out of the box as cast they flow between 260-270 cfm and are only a 170cc head, worlds better than a factory hump head that if you're lucky might flow 200-210 cfm, and that's a big valve version.

Trick Flow also incorporates a more modern heart shaped chamber. They are super nice pieces for a stealth build

Hoping these new RAIV aluminum heads follow the same path, if so I'll be picking up a set.
