Weiand Stealth 8022 - bad ports, can it be fixed or should I send back?

When I last raced the 8022 was the spec intake, I have 6 of these things, all were new and they are just plain crap. No grinding or porting per the rule book, I ended up grinding the worst ones and prayed to hell I never got d/q ed. People talk about the speedmaster s being crap, I've had 3 of them, they are jewels compared to the 8022!
