Finally had a chance to watch the video. Attention needs to be paid to the exhaust ports if one wants to make big power with a d-port head. This isn't breaking news it's always been that way. Pontiac figured it out in the mid 60's.
Curious what folks opinions are with a trade trading power for conviencece when deciding between headers and manifolds?
With tuned collectors the headers would've been good for about twenty horsepower and two tenths at the track.
