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.
