I've had the info for a while, but I haven't had time to make the post. A few weeks ago Stiegemeier flowed a set of Coy Miller Stage II heads on the same flowbench and bore as he flowed his heads. The results, were the Stiegemeier heads clearly flowed better on both the intake and exhaust, especially at low lifts. And on top of that, Stiegemeier's heads are about $200 less.

The CMRE heads had to be redone because the teflon valve stem seals had pulled up, causing the engine to burn oil.

I didn't put this post up to start any flame wars, but it was info I had just lying around, so I though i would share. here's the flow comparsion.
