Slant Six Buildup Ported Heads
|
We replaced the old head with a ported head from Mopar Performance. This head comes fully prepped with 1.70-inch-diameter intake and 1.44-inch-diameter exhaust valves (PN P4529821). Before installation, and because of our higher cam lift, we had the top of the valve guides milled to prevent any damage. Here, Dave lowers the head into place. View Related Article
