Factory HEMI Head!

just wondering, how much hp does the Aussie hemi head make? is a copy of it the best idea?
No, the best idea is building an improved aluminum slanty head from scratch, and again there is no consensus on what it should be. If You design a cross-flow type head, the
market will be tiny, and it would be foolish not to go 4-valve at that point. Or, more practical, design an improved version that will accept std. manifolding, flow better, have
an improved chamber, and of course weigh a good 30+ pounds less. I am working on ideas that would permit flexibility between stock apps & very hi output projects, but
ideas are a long, long way from reality. Time,$$$,R&D,& collaboration are all needed for anything to get close to happening. Lately I haven't haven't had much of any of these!
