I'm probably gonna get waylaid for this, but, here goes. I've disassembled a fair share of 5.9/360 Magnum engines. Most right at the 100k mark. Those usually only require a re-ring and fresh bearings, i.e. very little machine work. IF you are super lucky, the heads won't be broke, most are. The best bang for the buck will be the ch318b EQ's as RAMM suggested. The money you would have stuck into rebuilding the stock magnums can buy the eq's. That's not to say they don't need a little help out of the box(guides to tight). They are better heads than the stockers. If the lifters check good, they can be reused. Other pieces are tit for tat. Point being for the same money, or even less, you can do the mag versus teen.
