Does anyone have any experience with the Gude head package for the '90 dsm turbo? It sells for around $1400 shipped and comes fully built with cams, valves, guides, springs, ported throttle body, ported intake manifold. It is a completely done head ready to bolt on and Gude claims 45% more horsepower to the wheels. How can this be for $1400? The closest head package that SlowBoy makes is almost $1700 and doesn't come with the ported throttle body or the intake manifold. Please advise. Thanks
