Old vs New 360/5.9

Check out Engine Quest iron replacement heads. The bare castings can be had for about $600 and flow better than the stock, very crack prone originals. Look at the thread " another 408 build" for head flow #s and dyno info from my 408 striker( 4 inch crank in a 5.9) I think the Magnum motors are a great motor. Lots of advantages for up to about a 550 hp build.
