I didn't do a build thread on the magnum but there is some info in my user profile. I do have a turbo build thread in the Forced Induction category, but don't take that route if you're on a budget. But I basically followed the LXGUY build. Same guy with the magnumswap website. Used the same head gaskets, push rods, etc that he recommended. Had my cam reground by Oregon camshaft which was cheap. The EQ heads were the biggest expense. If your heads are good, then you can hopefully skip that expense. Mine had the typical cracked valve seats but I've read that they will still work.
