Coated Dart heads?
He also doesn't use the Dart valve train parts. Not to say what he uses are bad, but the Ferrea valves are a little heavier then the forged one piece valves Dart supplies and the 918 springs, in my opinion, are inferior to the PSI beehive springs that Dart supplies with their assembled heads. That is also a lot of flow, not sure what the port volume is on them. I believe he buys the bar castings and sets them up himself. I have seen good reports on his setup though.
They seem to be a very reputable vendor from everything I have ever seen on them.
