Actually, the Magnum heads are some of the best breathing heads Chrysler has
ever made. I think the W5 heads are derived from the Magnum combustion
chamber design, but for bigger valves and greater valve lift.
I didnīt know the new heads would bolt up to the older blocks... I thought
there-
were a few bolts in different places.
Anyone know whether thereīs enough wall thickness in a 318 block to bore out
to a 340? Or is it better to start with a 360 block?
