Ok, got these questions answered in another post by scratchinfotraction (thanks mike you da man!) But I want to keep this post alive so I can do an illustrated how to, so if your interested, mark this post in your favs and keep your eyes peeled

Here's what I got and what I'm gonna do: I have an 86 LA 318 with a factory roller cam. I am to going to swap my LA heads for Magnum heads.

Parts list:
Mag heads, complete with rocker assemblies
Mag push and roller lifters (need these because my LA does not lubricate through the lifter and pushrod)
Mag intake
New roller cam (I could keep the stock one but I wanna upgrade to a better cam)

This should allow me to use everything I already have and upgrade my cam and heads for minimal cost. The parts hunt will begin this week. I will post pics of the parts as well as estmated costs
