Magnum 5.2l vs 360 LA?

Main question is what do you want, 340 top end or down low grunt? I like the efficiency of the 5.2. Heads should be equal or better, depending on year. Magnum heads are prone to cracking, larger valves, better chamber, 5/16 or 8mm valve stems, and 1.6 rocker arms. Internal balance, decent compression, roller cam. What's not to like, should be a nice quick engine in an A Body.
