So, I was considering - down the road - of purchasing this package to upgrade my 440. In perusing YouTube, on an unrelated topic, I came across an individual who had posted a very critical video of Hughes products (heads, in particular), and it wasn't good, to say the least. Therefore, I'm tapping into the FBBO crew for some input. If not, Hughes.. then what have you used, or what would you recommend? To keep it consistent, I'd be looking at ALL of the components that come with the Hughes package. Thanks!
