I heard Hughes has the heads that are patterned after the Magnum's but also take the LA valvetrain/intake and rocker setup. Which part number are these?? The ones I been seeing on the site say "direct replacement for Magnum truck engines" ...??

I'd like to have something with the flow advantages of the Magnum and the rocker/valvetrain setup of the LA engine. For the money, it seems hard to beat.
