Valvetrain oiling has to be considered, but there are solutions to use mag heads on LA or LA heads on a magnum.

Regarding the intakes: there is a Indy 360-3M intake available with mag-style bolt pattern, so this is no deal breaker.

The Indy 360-3m is the best magnum intake out there, that's what I use on my Magnum build, it was heavily ported by Shane Studley, Precision Cylinder Heads. He was not impressed with it out of the box. I'm using Bam Solid rollers and Jesel shaft rockers for the reason you mention....640 lift cam.
