Best iron cyl head?

Thanks. I am considering this head to swap onto my Magnum's, 5.9 Magnum engine but would like to use LA intakes and Magnum rocker gear. This combo is available correct? And can use Chevy rocker gear.

Gezz, I'm starting to forget!

If you decide to go this route I built a jig to drill magnum heads for the LA pattern. You're welcome to borrow it.
