Even the Chinese castings would be good if they would simply reduce the core size and build the deck and top side thicker. It's the almighty dollar savings, and hoping that no one will run the high spring pressures and the tall lift cams. If i had my way all the alum heads i run would be solid, but i run alcohol and don't have a cooling problem.

How many Dart heads have you ever heard of pulling the entire top of the head out around the stud??? I've not ever seen one. How about a Brodix?

This is almost too funny and remember WJ, you found this set of heads. Appearently the rocker bolt boss broke out just like the CFE and some Procomps.

Yeah, and for all we know, it wasn't the casting's fault. Did you see the combustion chamber??? :shock: I'd say there were "other" issues with that motor that far exceeded what was seen.

I would bet there is what's left of the motor the heads were on...

6 pistons/rods, cracked block, no crank. :shock:
