magnum heads are an EXPENSIVE swap, and when you're done, none of your "old stuff" will fit your "new stuff" including cam and lifters, and intake, or rocker gear
Incorrect my freind. The cam and lifters are fine. He'll need new pushrods to meet the new Magnum rockers. In which an interesting choice comes up with the increased rocker ratio of 1.6 or the upgraded rocker of 1.7. Ethier way a new spring for the new lift height cam should be considered as well as a good look for coil bind at full lift.
After a resell of the older "LA" parts are done, the money gets rolled into the new intake. RPM or M1.
