Boy you guys had a little pissing go on in here. 

Kaase decided to build those heads when he heard what C&C Motorsport was getting for there race head and what the "old" OME heads were costing people.

I didn't read the link but when he was doing the R&D on them he was posting dyno numbers from his "mule" motor. If I re-call correctly his 520" 10.4:1 engine made 904 hp at approx. 6,400 rpm.
