You are all right about the VEs but this is how you see things now.
I don't think there are many people who will start building a DE from the bottom line to 160-170whp nowadays. In my case, I started 4 years ago. Modification after modification, 4 years of building an engine which should have taken me few months only. I wish I had the proper knowledge back in the time so I could go with the VE as well, instead of taking the long (and expensive) way building the DE.
