W2 Mopar inspection w/RAMM

RAMM would have answered it better and fuller. I'm sure if it needs to be added to, he will.

There have been by 2 companies. MoPar didn't bother and just let the other places do it for them and they were easy-ish to get. Batten and Diamond.
MoPar just kept with the cast iron since making the power with the iron material wasn't an issue. It is super durable, tough as heck vs aluminum. There were also classes at the various race tracks that demand you run an iron head. Aluminum is a great weight saver and helps time slips in drag or roundy cars, it was not legal. It has always been expensive to run a Chrysler, even though it made more sense because they were making more power than the Fords or Chevies and the Oldsmobiles and etc... Making the same head twice out of two different materials is a huge PIA and expensive twice round for Chrysler.

Runnning A iron W2 has a weight penalty of approximately 50 lbs. or maybe a slight more? IDK, I could weigh a bare W2. Some will scream it is huge amount of weight, (I really don't think it is at the "END of the WORLD" level they portray it is) what makes it even worse than just simply the weight, it is also the placement, in the worst spot, up front, up high on the engine.

Any weight saved is exactly the same as adding more power to the car engine wise. It is also the same as a better suspention and handling. All of this free HP due to the heads material and weight there of is a worth while avenue to take.
On a street engine, or where your not worried about every last tenth, an iron head is just fine. Super durable! You'll have then past your kids growing up and handing them down to there kids....if they still make gasoline...or something to run them in the future....LMAO
