It seems that the stock manifold would be a bottleneck, but i think i remember toysrme's guide saying that headers would not make any power. Is this still what everybody thinks?
Where does the stock manifold become a major restriction? If your only looking at a somewhat mild build(300-400hp) is it worth the effort?
Would it make a difference if you want to go N/A, compared to turbo, compared to supercharged?
Is their some chinese pos company that makes cheap headers that can be made to fit right for these engines?

I'm using the factory Castiron "logs" and starting my custom turbo manifold below on their 2.5inch 2bolt opening. simple and sweet.
Not worth the effort to go tubular unless you go square tubing and that would look awesome (performance might be sketchy)
Proven: Headers don't make power
Proven: Headers are expensive (the good ones)
Proven: Turbochargers off the factory logs work awesome!
Proven: If it ain't broke, DON"T FIX IT!
