BEAUTIFUL HEADS!!!

It would be way cool if the valves were splayed both ways so they would fit and actuate in a true 4-valve hemi-head chamber and not what I figure is a pent-roof chamber...

But no matter....

Check out the web site for these heads!!
http://www.araoengineering.com/dnochrts/dyno_sheets.htm

They post some very very impressive dyno numbers. IT looks like the higher you rev them the more power they make. There never seems to be a decline. Ex 350 with preformer RPM 750 holley and a small hyd roller cam 225* duration and .514 lift made over 668hp @ 7500 rpm and over 500lbs of torque from 3000-7000 rpm. Here is a claim from their website "The unique valve gear arrangement made possible by Arao Performance's patented head design (US Patent #5,007,387) allows rev's to over 9000 RPM without use of exotic valve train parts or freakish valve spring loadings"

9000 Rpm ?? wow !!! you better have a strong bottom end for that!!!
