Gude might not be total ish... but I have heard of problems. It's supposedly a company for the meek and mild. They were a consideration when I was building my motor, but they weren't hard core enough. So I chose, of all people, JG Engine Dynamics. Although I've had my issues with them, my TB and intake manifold were extremely nice. And I absolutley LOVED my Pro series head. It was, in a word, badass. If I had it to do all over again, which I pretty much do right now, I think Portflow would be the company which I'd try next.
