Anyone ever run Speedmaster Heads on their small blocks

I have a set on my 340. I bought them bare and had them ported and set up with quality hardware. The castings looks as good as the TrickFlow, Ford Motorsports, and Edelbrock heads I've used. I don't see why they wouldn't be a good option for the street and street/strip guy. Just don't run the out of the box and don't expect them to run with heads out of their class.
