I wouldn't pay Hughes a dime, but I would talk to Dwayne Porter.
I spoke to him about the cam choice and porting.
The biggest reason I went to Hughes for the info is that they've flowed a bunch of different heads and have the numbers on their site. I like that better than looking at heads that were tested on a hundred different machines all over the world. I'm a data guy and a single source makes for a better A/B comparison in this situation.
As for the fondness (or lack thereof) for the company, that's one of the biggest things that drove me away from racing. There's a non-stop hate fest going on. Racers piss on one guy and put another on a pedestal while the next racer does just the opposite. It's as hypocritical as the 350 lb driver spending thousands to build a light weight race car while refusing to go on a diet himself.
