High CFM heads - What would you chose?

Might wanna do a little digging on that and see if you can find someone other than Hughes that can confirm their numbers for that operation.

I know Jesse Robinson’s results were quite a bit less than what Hughes was showing.

I’ve had some Hughes ported heads on my bench...... some flowed pretty close to their numbers...... some didn’t.

Not that my bench is by any means the last word in accuracy....... but my numbers aren’t usually very far off from what is typically seen by other shops.
Ihad my bigmouth flow tested and they were just about on the mark , tje flow more than i need with room for improvement should i get a bigger cam and want to set the rev limit a bit higher . with the right cam and intake I'm sure i could get close to 600 hp , i'm at 510-520 now my setup now drops off at 5300 rpm , i want it to peak at 6200-6500 rpm
