I was talking about the valve springs and cam specs, I did not certify the entire thread as being to your standards. Feel free to post any relevant info helpful to the OP that you can find on the web.

400hp with untouched magnum heads is stupid simple and easy.

No need for porting, no need for overly lumpy cams, no need for anything trick, special or made of unobtainable. Or particularly expensive.
