340 heads
Yes, well maybe this X calls for some more explanation.
It is not that the X means you can use them on any engine… The X refers to, as seen in this picture below, the X in the casting.
The X-head was found only in 1968 and 69 on the Mopar 340 engine. Some early 1970 engines had them too as I understand it, but I can´t verify this out of my own experience. They are considered to be the best head Mopar ever offered on a small block engine from the factory.
