Stealth, RPM, 906 heads

OH! HEY! No problem, make money first! I like dead pres's myself. I think there my best friend. No complaints, zipped mouths, leave when I tell'em to....etc....

I'd like to know for surely how they are when ported if you have that info. OOTB info would be cool, but, ported is the big question in my head. NO ONE seems to know much of anything about these heads. Also, by chance, would you know the port sizes in cc's? And at what amount of inches there flowed at?

Thanks IQ!
