I know that... I'm looking to build a 6.0 block soon and wanted to know if they'd be worth buying.

I would say yes. Of course, I'm somewhat partial to rectangular port heads.

Ray,
Here's an interesting thread I ran across that Richard at WCCH was involved in a few years back regarding those heads. May be helpful.
