Others have experimented their way into the knowledge. I've noticed through the years that nobodys talking. Everyone needs to make a living, research takes time and money. The people that are willing to pay for the set-up info are the ones going faster. As David Vizard (cylinder head guru and author) told me years ago:"any info that I will release in any of my books and articles is at least 5 years old, only the CUSTOMERS get the latest scoop. Free info is old info. TIMINATOR
