I'm getting ready to do a port and polish on my cylinder head and I wanted to take it another step. I was thinking big bore throttle body and high flow intake manifold. Obviously, the plastic manifold can't be ported. So I've been searching for companies that market these two parts. Gude is the only company that I've found that has these parts along with their cylinder head and cam. Well, from what I've heard, Gude is bad. Has anyone seen or heard of another company that's making these parts?
