I have learned that we are never through learning! Knowledge on these things is a progression (just like anything else on the planet). It is impossible to absorb "everything" quickly. I have leaned that MOST of what you read should be taken with a grain of salt. I have learned that there are a lot of smart people who can really miss it on Ford FE heads......I mean REALLY miss it. I think if I was "into" FEs for the long haul, I would buy some respected stuff, disect it, learn from it, and build on it. If I just wanted a one-time successful project, I would go out and buy it from someone who could give you human references williing to talk about their experience. The internet is a great place to interact with others of a common interest, and a great place to get burned if you are not careful. Never buy heads based on just a flow number someone spews out. Never compare dyno numbers from different dynos, and if you go to a machine shop to have your FE machined or worked on, and you don't see three or more FEs in there, turn around and go someplace else. My final two thoughts that pop up immediately are: (1) Sometimes, there is more than one way to get to the desired result. (2) COMBO is everything! You have to be able to define where you are wanting to go, and then hit on the right combo for the job.
