Aluminum heads on 6.7 ???

This article says the 6.7 has aluminum heads, that makes me nervous. Block is graphite cast iron.

Seems like aluminum heads are usually OK until you overheat, but I think they are risking a lot of trouble.

Seems a little bizzare to me with all the 6.0L head problems they had, and those heads are cast iron.

If they want it bullet proof, why not iron heads and studs instead of bolts. Hope it doesn't end up being another Powerjoke. Wonder if Destroked is already working on a conversion?

The d-max has aluminum heads, and we all know how much power they can push. Aluminum heads should be the least of your strength worries, take a look at the how they make the blocks

I'm not worries, I think this engine WILL set the new benchmark for the other two to follow, and with the d-max being a thing of the past soon, who the hell knows what will happen in the diesel truck market

What do you mean by this? Chevy and Isuzu not collaborating anymore?

That's what I heard

Quote:

January 30, 2008 - Isuzu announces complete withdrawal from the US market[2], effective January 31, 2009. It will continue to provide support and parts. The decision was mainly affected by slowing sales. Isuzu had been experiencing a slow decline since the late 1990s. In less than 10 years, they had gone from selling a complete line of cars, trucks, and SUVs, into being a specialized SUV maker, and finally selling only a pair of rebadged, General Motors Trucks. [3] They will continue to sell commercial vehicles in the U.S. [4]

DMax makes the Duramax and its made here in America. Izuzu had a joint venture with GM on producing it and forming DMax, but I don't think they have much in it anymore.

I guess we are kinda getting off topic, but ya all got me curious about this. Here is a link about it all. Sounds like from '06 on the DMAX is made by GM only and all the design changes from then on are GM.
